"Do we have Tomb Raider? Crysis? Bioshock? GTAV? No? Well at least we have Aliens and Rayman! Phew!"
Is it just about having them though? Look at Nirolak's list, it's pretty impressive:
Assassin's Creed 3 - Biggest AC ever
Call of Duty - Best selling game in the most popular genre. WiiU version not gimped, some people actually called it the definitive version
New Super Mario Bros. Wii U - Other NSMB games sold 20+ million, it stands to reason to think this would be a huge seller as well
FIFA - Go to soccer game. HUGE in Europe, getting bigger in the US
Madden - If you want to be successful in the US you better have a non gimped version of Madden
What if they had Tomb Raider? Or Crysis? Or Bioshock? Or even GTA? Would that really matter? You can get them on much more popular platforms that are also significantly cheaper and your friends probably own one of those as well so you can play online with them. When MS was trying to get the 360 to be the beast it is today it moneyhatted BIG franchises. Tales, Star Ocean, GTA DLC, Elder Scroll, Bioshock, Left4Dead, Gears, and more ALL announced to be exclusive for the 360 (of course we later found out all but the latter 2 were just timed). Not only that, but ALL previous "Playstation" franchises were brought over and released day and date with the 360 version. RE, DMC, TR, FF, and eventually MGS were all released on the 360 the same day.
If Nintendo wants the WiiU to turn around they would need to pull something similar, as the tablet controller is NOT the wiimote and the WiiU certainly ain't the Wii. Imagine, if you will, that Nintendo had been aggressive and Watch Dogs, Destiny, mainline Tales, SOV, GTAV DLC, Bioshock DLC, and others were all WiiU (timed) exclusive, on top of getting all major franchises on WiiU day and date with Sony and MS' consoles?
