Yeah while I'll agree that Fifa (EA) have improved the playability of their football (soccer) series, the years of releasing sub par updates has hurt their reputation and means that Pro-Evo has a bigger appeal for footy games fans..... Most people I know that buy Fifa tend to use it more like a management sim and stuff because of the roster...
While every where you go Uni campuses after work events and stuff, barbecues whatever, you'll always come across people challenging each other to a Pro-Evo match.... So if they pull it off for the Wii and I think they'll see mario strikers and fifa and come up with a good control scheme, This will cement the Wii as the best all round system... Less of a reason for me to have two systems this cycle .........
I was forced to buy a PS2 alongside my gamecube because of Pro-Evo and streetfighter, didnt want to be left out the loop, got tired of loosing when the boys would meet up for a game of Pro....
