Mario Strikers Charged is a very fun game with many things going on at the same time. Should keep you busy for a while.
There are alot of characters in the game which are the captains of each team. 1 thing i don't like it that you can't have 2 of your favorite characters on the same team. For example, Mario and Luigi can't be on the same team. They are both captains, so they each have their own teams. However, you can change and modify who your other team members are. The other team members are called "sidekicks" but they cant be other captains.
I think there's enough in the game to keep you interested for a bit. The single and multiplayer aspect of the game are good. Online is very good, considering it is the first online game for the wii. They did a good job.
When playing for the cups, the matches start out easy but get increasingly difficult.
Over all I realli enjoy this game and I would recommend it to just about everyone.
