===Key differences between 40k and 30k===
30k is a very different beast to modern Warhammer 40k, despite not looking like it on the surface. Firstly while <s>9th</s> 10th edition 40k uses AoS as it's basis, 30k uses 7th edition 40k as it's basis, which means many things that disappeared from 40k are still around in 30k, most notably Armor Values for Vehicles (except for Dreadnoughts and Land Speeders, which have Toughness and Wounds like infantry), <s>Universal Special Rules</s>, paying for wargear, Initiative and the Weapon Skill of units interacting with each other. These differences means that Horus Heresy plays much more like the older editions of 40k, with a lot of the same caveats. The direction of tanks is important both to keep them alive and because their guns can't magically shoot through the tank to hit someone on the other side. On the infantry front, you need to be more considerate when you pick targets for shooting, since you can't fire what ever you want at how you want. Everyone must shoot at the same target, you can only charge units you have shot at, and you can only charge after shooting if you shoot Assault or Pistol weapons or have not fired your weapons at all.

One of the big differences between 40k and 30k is the community approach to army building and theming (discussed in further below), as 30k is pseudohistorical and the 30k community has become more focused on balanced and fluffy army lists over hyper-competitive army lists. As a result army lists designed to purely crush your opponent and not built around any sort of cohesive army theme are not well tolerated by the existing 30k community and failure to comply with the social standards put in place will get you labelled a "prick" and no one will want to play with you. This scenario can easily be avoided however by simply picking a theme, painting your models and not being a cunt while building your army list and actually playing the game.
