Nintendo fans should actually be quite happy that all those mainstream games wont show up on WiiU I mean the only thing they get from this is more "fake" gamers (added to the already huge number of "casual" gamers) and the result would be more streamlined games with less brain needed to finish them.
COD 3 sold slightly better on 360 compared to Wii in 2006 (because 360 came out in 2005 and Wii in 2006 = 360 more owners)
Then they skipped Wii with ModernWarfare the most important installment of the whole franchise (it came out 2 years later but that was way to late because most Wii COD gamers moved on to PS360) that was the reason why the game never became a huge HIT in Nintendo platforms.
And with every new installment ignoring Nintendo consoles they fuck up their own situation even more and have to start from scratch establishing their IP.
I mean the most important game in the series that made it a hit was absent for 2 years and forced people to buy other systems. And then they have no constant releases for the franchise no wonder they struggle.
Why would I buy a game when I have no Idea if the sequel will come out and when I have no idea if the game will ever have a good multiplayer community etc.
Third party is full of industry idiots that calle themselves EXPERTS that forgot how the industry started. It tkaes effort hard work and time to win over new customers. Now they just see EASY MONEY vs EFFORT so they go for easy money.
Seriously if porting COD to WiiU would cost 1 million dollars and thy would just earn 500k then its still worth it because they are establishing the franchise on another console! And the next time you will earn 800k instead of 500k and the third time you wil lstart to make a profit. But they dont get it....
Just look at the sales of WiiU titles and compare it to PS360 sales. Black Ops sold 2.2x (or was it 2.5 times?) better on PS3 when you think about the copies sold VS consoles existing.
A game with no userbase on WiiU just sold half as much as the same game on system with millions of COD gamers where the franchise already established itself.
Mass Effect 3 on WiiU sold identical or even slightly better compared to PS3 even tho the WiiU version came out when the trilogy for PS360 was already announced! (again you have to see the how many games WERE sold compared to how many could be sold = number of WiiU owners then you have REAL sales numbers)
WiiU has a 22x smaller userbase than PS3 or 360 yet the games sell identical or better (Sonic Allstars) or slightly worse COD (becauase of the non existant WiiU community etc)
But whatever I and most people I know buy Sony MS and Nintendo consoles for exclusives because those are the best games.
