Numenera

Numenera is a RPG game from Monte Cook that was crowdfunded on kick-starter, and represents a significant departure from traditional stat based role-playing games, namely by letting players do all the dice rolling so the GM can focus on the narrative.

Setting

Numenera is set in the "Ninth World", a bizarre science fiction setting depicting the far, far, far future.

Ostensibly, the game world is the planet Earth, but has moved on to the point that it is completely unrecognisable. The timeline places it about a billion years into the future, which means that the tectonic plates have shifted continents about, the sun has entered a different phase and the moon likely orbits differently. Not only that but the landscape has been twisted by extradimensional forces and strange technologies; rendering the planet completely alien when compared to us in the 21st century.

Eight different eras or epochs have risen and fallen prior to the start date of the campaign setting. For comparison; the Age of Strife in the Warhammer 40,000 universe might constitute the transition between one age and another where so much history has been forgotten about by the time the next era comes along. Numenera has had so many of these successive collapses of civilisation that attempting to accurately establish what relation "now" has to "when" becomes nearly meaningless.

The technological mastery of previous ages is barely understood, and is seen as something akin to magic. But remnants of previous civilisations are lying around all over the place, making up the "Numenera" that characterises the setting. These objects take a huge variety of forms:

Artefacts, are powerful devices that perform miraculous functions: be it small items like energy swords and medical implants, all the way up to extradimensional teleportation devices and flying cities. Artefacts are generally the most sought after or reliable devices.

Cyphers are typically small devices that perform a specific, albeit poorly understood function and tend to be used as healing items or weapons. They function in such a way that they generally do not survive the first use, often because they end up being used as grenades or because their power supplies get used up. They also have a tendency to react badly with each other, so it is ill-advised to hang on to too many at one time, due to unpredictable effects. Though Cyphers literally can be found anywhere.

Oddities are curious devices which have little to no useful function to an adventuring party, representing the everyday technology of former ages; like self-knitting clothes, levitating stones or music boxes that only the owner can hear. Clever gamers might find a use for certain items, but generally speaking, they exist for narrative effect more than mechanical function.

Mechanics

As mentioned earlier, the game revolves around the players rolling dice rather than the GM.

Numenera uses a D20 ruleset, but unlike D&D where having escalating skill modifiers which can eventually render the D20 itself superfluous when they can comfortably overcome any low level encounter without even rolling; or simply level up equally to challenge rating so any +1 bonus they gain is countered by a +1 to the level of the encounter, cheapening their progress. Instead Numenera players modify the difficulty of the test based on their skill.

The dice mechanic of "Difficulty" is simply three times the level of the encounter. So a level four encounter would need a dice result of 12 to beat. This also means that anything over level seven becomes literally impossible to overcome without using modifiers, as a 21 cannot be rolled, and levels go right up to ten, meaning you'd need to roll a 30 on a D20.

Being skilled in a task allows you to reduce the level of the test according to the level of training. Although there is only "Trained" and "Specialised" so using skills to reduce difficulty can only be done twice at most, dropping that level seven task (21) back down to level five (15), making it more manageable.

The main feature of Numenera is the the "pool" mechanic: each player has three pools of points, Might, Speed & Intellect, and they can spend points from these pools as "Effort" to reduce the difficulty of tasks, with higher level characters being able to spend more points on given tasks or use "Edge" which accounts for free points of effort before they even start spending from their pools.

The pools are renewed after resting, but can be spent on pretty much every test, meaning players have to manage their resources carefully from day-to-day. Even at higher levels when certain tests or abilities begin demanding more and more expenditure of points.

This also puts the onus of management on the players, meaning that the GM has to trust his players not to lie or conveniently forget to spend points.

This also means that in combat, players roll against themselves using their defense skill in the relevant field. Though attacks against them are measured the same way as any other skill. A level three opponent attacking a player would require the player to beat a 9 using their defense stat, and a 9 when attacking them in turn.

FATE d20 edition, basically.

...Okay, expanding. Basically, rate all tasks on a scale of 1-10, then multiply them by three to calculate DCs. So, a difficulty 1 test requires you to roll a three or greater on a d20, a difficulty two a 6 or more, and so on.

You may ask, well, how the fuck do I ever pass any tests with a difficulty of 7 (DC 21) or greater? The answer is training, assets, and effort. You can have up to two levels of training in any given test, whether it's trying to figure out how to hack through a door, shoot a robot with a gun, or convince an ancient energy being to help you survive in space, each one reducing the difficulty by one step. Note that being "specialized" (having two levels of training in an area) often requires being higher level.

Second, you can have up to two assets that further reduce the difficulty. Whether it's a rope that's helping you climb, a shield that's helping you block, intimate knowledge of the cultural practices of energy beings, whatever, they help reduce the difficulty of the test like training.

Finally, if all else fails, you can spend effort. Characters have an Effort rating, that goes up as they level up. By spending points out of their stat pools (more on that in a sec), they can further reduce the difficulty, though doing so means depleting what essentially amounts to their hitpoints.

On that note, stats. You have three: Might, Speed, and Intellect. Each day, you have a set number of points in each pool, and you may expend them to activate powers or apply effort. Since they are also lost if you take "damage," you are effectively spending hitpoints. To mitigate this, you have Edge in some of your stats. Edge reduces the points you need to spend from a given pool once during an action. For instance, if you need to spend one point of Might to active your Slice power for extra damage, and your Edge is 2, you instead don't need to spend any. However, if you also use Effort to try to deal more damage, you'd only reduce it by 1, since you already used up some of your edge on the Slice.

Finally, all tests are made by the players. Monsters don't roll to hit you, you roll to dodge their swings. Each of your stats has a "defense" associated it, with Speed being the most common, Intellect working vs. mental attacks and Might vs. poisons and the like. You can gain extra XP from "DM intrusions," little bad things that happen, or spend your own to make them go away.

Character Creation

Each player picks a Descriptor, Type, and Focus. Essentially, you should be able to describe your character, according to the book, as an adjective noun who verbs.

Types are the easiest to explain. They are your class. Glaives are fighting men, nanos are techno-wizards, and jacks are skillmonkeys who can be built to do a bit of either. All of them pick up different tricks as they increase in level. Naturally, this being a Monte Cook game, glaives get a few tricks to be marginally better fighters, while nanos get the ability to throw literal mountains with their minds.

Descriptors are like a 5e background, and, in fact, very likely where that mechanic originated. They are a bundle of skills, benefits, extra items and points, etc. Things that give your character flavor. Some of the more powerful ones also have "disabilities," making tests one step harder for you.

Finally, foci are where the sauce is. A focus is a bundle of different powers that you get as you level. From turning into a werewolf to throwing lightning around with your mind, to just being a sneaky bastard or dead 'ard, this is a large part of how you specialize your character.
