The game is slightly more psychotic than the GameCube version, if you have played that one. Everything has been improved: better AI, customizable sidekicks, better arena selection, arenas that affect you and your opponent's abilities, goalie control mini-game for Charged shots.
The AI in the single player modes are definitely putting up more of a fight. The challenge mode actually gets difficult, and the first cup starts off slightly difficult. They had me on the edge at moments. I think it comes from the addition of the evasion abilities when you have the ball. The arenas might change up your strategy up a little. The goalie mini-game is kind of decent. I just think it would've been cooler to hold your arms with the nunchuck and Wii remote and block shots that way.
Online was pretty lag-free as long as you're above 4 stars (or is that the highest?). I played three series, lost all three, but there was no lag for the first, lag for the second, and lag in the beginning but it disappeared for the third. Online is insane. People are ridiculously good. It boggles my mind. I beat people to a pulp in the GameCube version, but on the Wii, I got 2 wins in those 9 matches.
You know, I'm glad there's no voice-chatting enabled in Wii games. Strikers is one of those games where you really want to yell out obscenities at your opponents...
