If you can say the games that launched with WiiU I can try and say what I think of it. But my memory of WiiU the complains weren't about the launch, but that it got big draughts after (and Nintendo said it was due to they not being used to HD development), to the point a lot of Nintendo big fans skipping the console (although my friend loves his and is his favorite console all time).
The Wii U launched with New Super Mario Bros. U, Nintendo Land and ZombiU as their main exclusive games. Other than that, it was filled with multiplatform titles like Batman Arkham City, Darksiders II, Tekken Tag Tournament 2, Call of Duty Black Ops II and Assassin's Creed III. Some of these multiplatforms had exclusive features and gameplay improvements... and some came out months or even a year after their PS3/360/PC counterparts. And as I said, people regarded Wii U's launch lineup as disappointing.
I see many similarities in they kind of exclusive games both consoles got and the kind of multiplatform games third parties put on them. I don't know, maybe I'm being paranoid xD
