I have Pro Evo Soccer for Wii, and I've always been a great fan of PES, and it's definitely a LOT different than the typical soccer game experience, but it's great. Very, very, very innovative. FIFA has, for me, always been a follower and I daresay the Konami has outdone EA again in the soccer games series.
Mario Strikers is good multiplayer fun, but it's pretty shallow. It took me about a day to get so good that no one could beat me anymore... meh.
