Kingstar, I own 3 Microsoft games. Combat Flight Simulator (Jane's WWII fighters wasn't available at the time), Close Combat 2, and Metal Gear Solid PC. However, since those games are definately the minority, and were created by other developers, and simply published by MS (except for CFS), I wouldn't include Microsoft on any list of the best developers.
I really have to doubt the sanity of the person who voted Sony though. He must have really loved ICO, Twisted Metal, or Gran Turismo, as those are really the only Sony games I can think of that sold very well.
Now Lord Kane, as of the last count, I think that Xbox was leading in kid's games, then came PS2, and GameCube had the least. But that was a couple months back, so I am not sure anymore. At any rate, I don't see any notable difference in the level of maturity on the 3 systems. Most of the excessively violent games are multiplatform anyway. Except for maybe Resident Evil or Eternal Darkness....
