you're right that they don't make many games i care about. in fact, they make one: zelda. and you're right that i wouldn't see a bethesda game on wii or something, sure. but they still did win in third party games. no, they didn't win in high end graphics games (of course, other consoles only do better sales on such games, pc wins)
the last controller i really liked was the n64 one. yeah it was weird but it fit my hands nicely. i never liked ps controllers, i never liked the two thumbsticks. xbox was okay (i have a 360, haven't played it in 3 years). i perfer the wii + nunchuck over the xbox, but i'd admit it would be terrible for twitch shooters. but so is the xbox controller; get a mouse you heathen
