Jump! Superstars

I have my own copy and I unlocked all of the characters in about two and a half weeks after starting. The actual fighting is more like a standard 2D brawler, so there isn't much depth but you do have to keep in mind certain things like recovering from a double or triple jump will take longer than just one jump. After you unlock all the komas the replay value is almost gone unless you have a friend with a copy to do any multiplayer battles. You can do VS. Computer matches but even on the hardest difficulty setting it's still kinda easy because the AI still runs at you while you ready your special move but they can be kinda tricky if you mess up in anyway. I can only advise getting this only if you have a friend who has it or will get it because the fun will last almost forever if you have a friend to fight with.

Jam it back in, in the dark.
