There's this game I remember seeing at a skating rink a long time ago. It looked fun, but I don't think I ever played it. The details are a bit blurry, but here goes.
It's an overhead action game. I remember it being similar to a beatemup. I think it was fantasy themed. It was definitely multiplayer. Each player was a different color, like red, green, blue, or yellow. It was mostly melee combat, possibly with spells thrown in. As mentioned in the title, it was isometric or similar to isometric.
I know the obvious answer, but it is NOT a Gauntlet title. It seemed like something a Japanese developer would make.
<EDIT> Whoops, I thought I clicked the Arcade section...
