One of the most badd-ass games from last generation made portable.
Another reason to like the PSP.
Just check this fan-made gameplay demostration video and tell me it's not one of the most freaking awesome games you ever seen.
Picture SHENMUE meets DOWNTOWN NEKKETSU MONOGATARI (RIVER CITY RANSOM) meets TOKIMEKI MEMORIAL and you'd be getting close at just how awesome this game is. Seriously.
By the way, the same dude also did one for the third game, which was localized as BAD-ASS RUMBLE (fit name).
Personally, I liked the first game more than the third (main character isn't as likeable in my opinion). Of course it's still freaking sweet the third one got localized.
