I'd definitely recommend a HOTAS for this game. Kb/m is dreadful, mostly because they just have really odd movement controls. Sure, it's technically more precise for PvP, but it might be less fun.
Controllers are a bit better, but you might need double or triple bound buttons. HOTAS is nice because you will have fewer double or triple bound buttons.
I hate cars, but we've also allowed people to build developments in absolutely idiotic places that either need cars, or perhaps private bus systems. All because some idiot developer built a ton of grey, prefabbed houses 30+ miles away from the city in the middle of (what used to be) untouched forest.
