None, because DRM is bullshit and I'd rather play games on a console where I don't have to deal with it. Yes, even RTS games. I got Red Alert 3 for my PS3 instead of PC because of EA's SecuROM nonsense, and now I'll be skipping Command and Conquer 4 because of their Ubisoft-style "internet connection required" DRM.
Yes, it does suck playing with a pad, but you get used to it. Plus, there's really no reason why they can't allow you to plug in a USB keyboard and mouse other than their current phase of pride where every developer is SURE they can make their console RTS be the Halo of console RTS games. But hopefully, someone will give up on that nonsense and just allow keyboard and mouse support, causing other developers to follow suit.
