Haha, well the gamepad does have it's advantages. I like the Xbox 360 controller because it's like the Controller S, but better. It's so light (even the wireless one with batteries) and it has so many great features.
RPG's are still pretty fun on consoles, look at The Elder Scrolls IV: Oblivion. RTS's are obviously for PC's, where the mouse and keyboard works best. FPS's are a matter of debate because some prefer the mouse and keyboard and some prefer the gamepad. I like both, but what makes me like console gaming is the fact that I have a couch to sit on.
That's more comfortable than my computer chair.
