You are still missing the point. That games you list will go to the largest userbase at some point and time. It has nothing to do with the controller or specific people who buy that system. It is a vicious circle. More hardware sales = more 3rd party games = more hardware sales ... and repeat. This happened on the last two ps's. If the current trend continues it will happen on the Wii. Then all those people who bought the ps2 will probably by a Wii as it will have the games.
You still have ignored my RTS post. From what it sounds like the x2 game could be put on the Wii using the Wiimote as a mouse. Sure more people might not have liked the mouse on the pc version, but if that was the only choice then you would use it and still like the game.
