One of the reasons i still keep my gba sp around. This game is magically deliscious!!!!!!!
It basically takes all the fun stuff about being a super hero and packs them into a little robot that you can level up as you find people to meet. The lasers and jet boosts, along with normal kicks and punches keep the game play fresh all the way through. Not that i've gotten that far, since i've been stuck on playing final fantasy III, but i play it when i have free time. I'll be dedicating a lot more time to this game once i'm finished with FFIII.
If you have a friend that is burnt out on his or her GBA, show them this game, it will make them remember how fun playing the GBA can be. If your looking for a new game for your gba collection, for sure pick this one up. I've never seen or played this game on any other system other than the GBA, but if they are as much fun as this one is, i'd say hitmaker has done wonderful.
