Krypsyn: Generally, if it is a multi-platform distribution, I make the PC Vs Console decision based on how I want to play the game; PC for mouse, PS3 for game-pad.
StingingVelvet: GAMEPADS WORK ON THE PC OMG! #SOFRUSTRATED
Anyway...
Right. But, usually, I buy games that I want to play with a keyboard and mouse for the PC, then I buy everything else for the console. So, at least until this point, there has been zero reason for me to buy a gamepad for PC.
However, if a game game out that was better for a gamepad, but that had really nifty modding tools I wanted to take advatage of, then I would probably buy a gamepad for my PC. I don't think this is very likely though, since the more console oriented a game becomes, the less mod-tools become available (supply/demand type thing).
Fallout 3 and Fallout: New Vegas come pretty close, but I would still rather use a mouse and keyboard for them. If they ever become equal or better with a gamepad, it will be a tough choice (couch beats computer chair, if gameplay is equivalent). If those hypothetical games are based on the same engine, I don't want to get anywhere near them with a console. I have had to use console line commands (AKA cheats) several times in Fallout: New Vegas to correct bugs (once reset a quest trigger that would fire, once to noclip after getting stuck on the architecture, and once to reset Traits that had randomly decided not to work). Console commands can't be accessed on a console (kinda amusing, from a semantic standpoint).
Krypsyn: also, a counter-counterexample for Delixe; one where the PC/Mouse is better than a gamepad:
Dragon Age: Origins.
Delixe: Bad example. DA:O was designed for the PC. DA2 was designed for the 360.
How is that a bad example? I thought we were just talking about games in general. You brought up Diablo 2 earlier, that was mainly a PC title when it came out. Same with TIE Fighter and the Wing Commander games, AFAIK.
Regardless, I never played DA2. The reviews were awful, I never even played the demo I downloaded on my PS3. I think it is still there...
