The Peace Keepers (it got a US release, I'm assuming you guys never got it) seemed like a decent beat-em-up, with a decent number of moves, branching paths, and multiple endings. The problem is that for the US version, they kind of screwed it up hard, by, among other things, removing all the music in the game and replacing it with ambient sound. The other two games in the series seemed... well, Rival Turf seemed pretty repetitive, and Brawl Brothers seemed all right, if it weren't for the sewer mazes. Yes. Sewer mazes. It's as fun as it sounds.
