If you want to play with a controller (2nd rate form of controlling games) play PS3 and Xbox games.
I really hate elitist staments like this from my fellow PC gamers. Are some of you people aware that most more PC games have Xbox 360 controller support? Are you people aware that Valve released a whole entire mode on steam with controllers in mind (steam big picture). If it's not some form of strategy game or PC exclusive RPG, then your average PC game has controller support.
I'm fine with this game having only keyboard and mouse support, but don't assume controllers are a console only thing.
Blame the greedy publishers that have decided that every single game should be playable on consoles (and as such, have controller support as most people don't attach a kb+mouse to their consoles) and in the process have ruined a *lot* of possibly good games and made next-to-extinct quite a few (sub)genres that rely very heavily on the mouse (like IE-styple cRPGs, C&C-style RTS, point & click adventures,...)
