D20 Modern

This article is awesome. Do not fuck it up.

What do you get when you take Dungeons & Dragons and put it in the 21st century? d20 Modern.

Back in the good old days of 3e (not 3.5), some brilliant bastard at Wizards decided that there was no point in having only one game using the d20 System. So, they took the D&D rules, replaced the classes, and added guns. The result was d20 Modern, an easy-(enough)-to-play modern RPG (if you don't mind rules skewed toward magic and monsters, as opposed to, you know, REALITY).

Like D&D, Wizards also belched forward a number of accessory books for d20 Modern, which, unlike the D&D supplements, were few in number and many actually worth buying. They still handled guns with shitty attempts at realism, but then every RPG does.

If you look carefully, you'll see some of the ideas from d20 Modern survived into D&D 4e, which some would say is a brief glimpse of win midst the fail, or just more failfuel for the failtrain.

Another nice thing that kept the guns SOMEWHAT realistic, was massive damage threshold. Instead of 50 like in D&D, it was equal to your Con score. This meant a critical hit or good roll from a long gun (usually 2d6 to 2d10 damage) could force you to make a save or instantly go to -1 hit points. If gun damage had been buffed a bit, it could have been a nice alternative to the "Vitality and Wound points" used by Star Wars D20. This was addressed in Saga Edition with a damage threshold system where damage in excess of the threshold's value caused a penalizing wound, which was relevant with higher damage, more starting HP, lower threshold and easier to increase gun damage.

Star Wars d20 was based on this system. While it solved a few of d20 Modern's issues, it unfortunately compounded many of its problems with problems of its own. Saga Edition adopted more ideas from d20 Modern and actually fixed everything.

Differences from D&D

• Action Points, like 'karma' or 'luck' points in other games. You can use them to either boost the number you rolled on d20, or to use a feat that requires an action point (usually to do something totally awesome). Action points spent do not return until you level up.
• You didn't keep track of how much gold/dollars/nuyen you had; instead, Wealth was a skill check, and getting big wads of cash was a bonus to your Wealth rolls. Purchases had a DC for Wealth checks, and buying something with a higher DC than your Wealth score (which was virtually anything not one use) meant you lost some bonus (because you spent beyond your means). It was horrifically, horrendously, broken. Not in the "overpowered" sense but "they didn't playtest this once".
  • Having anything with a non-trivial cost reduced your wealth bonus by at least 1. A starting character's wealth bonus is (2d4+1 to 4 from starting occupation+1 from having ranks in profession. Typically 7). A Computer (-2d6 because computers cost an absurd amount in this system), a printer/scanner (-2 because these are completely different items), filling out a 4473 form (-1), a shotgun (-1), a decent backpack (-1), and a single set of clothing (-1) will take a character from "middle-class" to impoverished.
  • It also has some really fucking bizarre ideas on how restricted everything is legally. Suppressors ($200 tax and a bunch of waiting) are, under the game's rules, harder to get than full auto (The same, but banned since 1986 so all grandfathered examples cost tens of thousands) while sawed off shotguns (Same as suppressors) are flat out impossible to get legally in the game's rules (and black market sawed off shotguns are several times more expensive than normal black market shotguns).
  • You couldn't take 10 or take 20 for wealth checks or take average wealth decreases during character creation, meaning you had to make your character with the GM present wasting everyone's time and rendering the OGL nature of the system moot. This was thankfully axed in errata.
  • Urban Arcana offered the option to play a reverse Isekai character. This gave you extra wealth (2d6+occupation+profession skill bonus) at character generation in exchange for having your bonus go to +0 afterwards (apparently the several pounds of gold a fantasy character carries is worthless in the modern era). This was hilariously easy to cheese since you could bypass the "magic items are rare" thing and buy expensive magic items (indeed, you sorta had too since there's little other fantasy appropriate gear at high enough price you don't get it for free) like a magic jacket that gave you DR10 against non-magic attacks, enough to pretty much nullify all damage for several levels (an attack would need to kill a 1st level character outright to even scratch you). Since wealth increased quickly at level up if it was low, this isn't much of a disadvantage in the long run.
• No alignment system; instead you had an "allegiance." You could have an allegiance to a religion, a nation (patriotism), an organization, a philosophy... and you'd get a +2 circumstance bonus when dealing with people that have the same allegiance.
  • In fact, you could have multiple allegiances, although most people were too dumb to take advantage of that fact.
• You had an Occupation, which was like your level 0 class that gave you some class-skills and maybe a bonus feat.
• There were three noticeable tiers for characters: levels 1-7, levels 8-15, and levels 16-20.
• Every class only has 10 levels; you had to take an "advanced" (read: prestige) class or multiclass if you wanted to go higher.
• There are six basic hero classes, one for each of the six base attributes: Strong, Fast and Tough heroes (Str,Dex,Con), and Smart, Dedicated and Charismatic heroes (Int, Wis, Cha). There's no penalty for multiclassing (indeed, it is required by level 11, see above). There were 12 advanced classes, designed as 2 for each basic class, but which could be taken by any character provided appropriate requirements were met by said character. Some splats added additional advanced classes, as well as some 5-level true "prestige" classes.
• Basic classes had no class features but got talents from a class specific list every odd level. Most were just plain old shit and the worst class features ever (You get +1-3 to a couple skills! If you take longer you can lift/bend harder!) but the system would eventually be fixed and made awesome in Star Wars: The Roleplaying Game Saga Edition before being made useful but video game like in 4th Edition Dungeons and Dragons.
• No spells/miracles/psi (called "FX abilities") for base classes. Only prestige classes can have them, and refreshingly little of the rulebook is dedicated to listing and describing spells.
  • Spellcasting classes are all advanced classes, so you can't enter till level 4, and like all classes only go up to level 10 limiting you to 5th level spells. Theoretically this makes them less powerful, but practically it just means any mage is a Gish or Arcane Trickster (especially so on the second since Mage gets loads of skill points even before intelligence bonus) to some degree and they're still the best classes in the game.
• Had several supplements, including d20 Future and d20 Past. d20 Future had rules for playing (you guessed it) in the future and also had several supplements (d20 Apocalypse, d20 Cyberscape and Future Tech). d20 Past, meanwhile, had rules for playing the past. Obviously. The supplements allowed players to engage in updated-for-a-new-generation games that Gary Gygax had put out, including Gamma World, Boot Hill, Star Frontiers, Age of Exploration, a Zombie-Apocalypse variant, and many, many others. Suffice to say, these supplements, unlike their counterparts in Dungeons and Dragons, were actually worth buying and checking out.
  • d20 Past is a fantastic reference for when things first existed and first became common and even had a bibliography of citations available as a download.
  • d20 Future however was utter shit, with horrific balancing both in "useless" (You can play as an android! But your ability scores suck and you lose three feats for a handful of immunities) and "horrifically overpowered" (There are feats to get two extra talents, which are better than a feat if you pick halfway intelligently, and you don't even need to have been in the base class.), has horrifically bad ship combat rules, most of the sci-fi gear is just magic gear but not magic, and hilariously includes the (already out of date and poor preforming at time of publishing) OICW as a high-end future weapon.
• Child character are explicitly playable, but it's impossible to complete character creation with one unless their dexterity was high or their strength really high. Fixed in splat.
• While magic items aren't excepted, mastercraft ones are trivial to get for someone who can craft, but GM's whims for one who can't, and give the same bonuses. This reinforces the only crafting skill worth a damn being mechanical, as that covers weapons, armors and vehicles.
• Oddly not changed is that you can't coup de grace with a ranged weapon. Reasonable with slings and bows, but the inability to shoot a tied up or unconscious man in the head at point blank is bizzare.

Spycraft 2.0

Crafty Games made a heavily modified variant of d20 Modern which was based off their previous system. Spycraft 2.0 improves many of d20 Modern's faults (including replacing the clusterfuck wealth system with issued gear as standard). It also assumes the genre is not Urban Fantasy, which was largely the default in d20 Modern, and focuses on (as you'd guess) James Bond esqe antics. Unfortunately Spycraft 2.0 had two big, crippling faults of its own.

Firstly nobody writing it understood how pointless a +1 or +2 bonus was (it increases the total chance of success by 5% and 10% respectively) and they're everywhere and treated like they're important. Coming from a system where a feat that gave +2 to two skills was well known to be one of the worst possible options in any moderately normal build, throwing out a bunch of options with +1 and +2 bonuses to skills attached was pretty lame and hard to keep track of.

Secondly all guns have a recoil value that's effectively a minimum strength value. This is quite a reasonable idea but the values make absolutely no sense and these values seem to be purely based on the weight of the firearm with little understanding of the characteristics of even common cartridges. This means 7.62x39 firearms (which has quite harsh recoil for an intermediate cartridge) tend to have less recoil than 5.56 (considered the mildest recoiling centerfire rifle cartridge in common use) firearms since their all steel construction weighs more. This is absolutely not the case in reality. Other crazy standouts being Glocks have insanely high recoil values due to their light weight while most versions of the Desert Eagle have values approaching half the Glock's. A Glock 22 in .40 S&W has more recoil than a Glock 20 in 10mm, which is retarded because having less recoil than the Glock 20 is literally the entire reason it exists (Female FBI agents couldn't handle 10mm and .40 S&W was developed purely to have less recoil). Even within the nonsensical system of recoil being primarily determined by weight (rather than cartridge), the scaling isn't consistent across firearms in the slightest.
