There's been mixed reactions from developers. Some highly praise the Wii U, others have disdain for it. From what I gather the former group is larger, though that just might be selective memory in motion.
As was the 360 and 'specially PS3.
Never understood what all the hubbub 'bout launch titles was anyways, 'sides how stereotypical electronics consumers are always in a damn-well unnecessary rush with everythin'. So long as some games worth purchasin' show up in the launch window I'm happy enough.
Really there has not been many gaming systems that has had a library of launch titles which appealed to everyone or defined what was in store for that system. I am impressed with the number of games that the Wii U has at launch. A lot of games for a Nintendo launch, sort reminds me of an NES US launch. I can still remember the N64 launch with two games. But with a Nintendo system it has always been about Mario and his fans. There has been only three games that redefined Mario for me, Super Mario Bros 3, Super Mario World, and Super Mario 64. The Galaxy games have been good on the Wii, haven't tried the Bros game yet. I am interested in what is in store for the Wii U and what the controller means with this next generation of Mario.
