Its seems like third parties have had a cookie cutter offering for all three consoles, and 90% of the time they are dissapointed with how their titles perform on Nintendo's consoles. You would think that after 10+ years of dissapointment trying to offer the same product on Nintendo consoles that you offer on Sony and Microsoft consoles you would try something different. A game like Zombi U proves that you can offer an exclusive for a console and make a profit as long as the budget is kept under control.
At the very least publishers need to real in their expectations of ports on Nintendo consoles. Ports on Nintendo consoles typically sell in similar numbers to that of the PC versions. The Wii Call of Duty games all sold between 500k and 2 million units, thats very competative with the sales of the PC version. Why is it these same publishers are perfectly ok with the PC sales but someone their isnt a market for their game on Nintendo consoles?
I would think that its obvious that the road to success on Wii U is going to be different than that of competing hardware. If Nintendo gamers only buy "Nintendo games and exclusives", as many publishers have suggested, then what are you doing offering a bunch of ports? Especially full price ports of games many months old. EA, did you really expect a year old release of Mass Effect 3 to sell well on the Wii U? Even though I am super happy that Need For Speed Most Wanted has come to the Wii U, I really dont expect exceptional sales. Its another late port. Anything over 100k would be respectable for a full priced port that came out months later.
If exclusives sell better on Nintendo's platform, then why arent you creating more of them. Obviously they cant use the 50-200 million dollar budget that they can for the AAA multi platform titles, but a solid exclusive with a 10-15 million dollar budget for Wii U is likely to find far more success than a port.
Im not saying that third parties should stop porting games, but be realistic with your expectations and understand the platform you are supporting. Actvision doesnt expect the PC version of Call of Duty to sell 10 million copies like the 360 version will, but at the same time PC will get games like Starcraft and Warcraft exclusivesly that have good success on the platform. Its time for these publishers to wake up and realize that the Wii U is its own market, and not just a third console to play the same games that Sony and Micrsoft gamers play.
