I have been playing this game with folks at work for the past week.

I was never a fan of the fighting games, but I have to say playing this game is a blast. Combo and Hyper Combo are fairly easy to pull off.

Besides the main arcade mode, there are also survival and time attack modes.

Many things such as character information, character BGM, character art and different mini-games need to be purchased with points from arcade, survival or time attack modes.
You can also get points from playing the mini-games.

I don't have all the mini-games unlocked yet, but my current favorite is the one from Lost Planet.

Overall, I think this is one of the (currently rare) awesome Wii games.
