This looks fun, I enjoyed the demo for it on PSP. It was like a gladiator simulation, which like most simulation type games has it's share of frustrations but once certain systems have been mastered the game becomes infinitely more enjoyable.
Actually the game is pretty fun, I mean the demo. I'm not sure when the demo ends though. At first I thought I got lucky like with another PSP game and got the game free but pretty sure its a very long demo. I like the customization feature.
