IMHO that list of games is laughable. At least in teh HUGE sense. When you say huge. what do you mean? in sales? cause only Zelda and Smash are really going to light up the charts. Bayo2 will probably do a bit better than 1 which isnt saying much. Toad is spin off of a game that is doing good but wont light the charts on fire. Yoshi isnt that big. Splatoon is an unknown but im not expecting much. X we dont even know when thats coming. some of those are kinda niche. Not saying they cant be good.
But to answer the question, that is up to each gamer to decide whether Wii U is enough for them. BUT going by intial sales im going to say most people DONT think WIi U is enough. Hell a Ninty console hasnt been enough since SNES days.
Personally no way i can own wii U by itself. Final Fantasy, Kindom Hearts, Star Wars BF, Mirrors Edge. Assassins Creed, COD?, Tekken?, new Mass Effect, Batman, Metal Gear Solid 5 are just a few games of the top of my head that i want to play. And that not even the exclusives(which IMO Sony has the best ones)
