You know, I figured it out.. well, I noticed it as early as the first GameCube game, but the Wii version really accentuated the fact that..
Mario Strikers is more of an arcade hockey game than it is a soccer game. If you look at it, there's (how can you say "there are"

) so many similarities that it's uncanny. First, the hitting in general. You get a penalty (in this case you give the other team an item) for hitting them when they don't have the puck (ball). They even allow the split-second grace period to hit someone just after they've gotten rid of the ball without penalising you. Not to mention the walls around most of the stadiums that you can bash people into - just like boards in hockey.
There's lots of other stuff - the charging up, the emphasis on rebounds, the seemingly small nets, the fact that it's 4-on-4, etc, etc. PLUS it's made in Canada by Next Level Games, AND the theme song sounds eerily like something out of "Hockey Night in Canada".
So my point is, give me my goddamn hockey game, EA! Or even 2K or let NLG make one since they're done Strikers.
