Power Stone is one of the great gems on the Dreamcast. This game was a breakthrough among fighting/action games. It is a 3D versus fighter, with tons of special moves, destructable environments, weapons and other items you can pick up and use, environmental traps and gadgets that can help or hinder you, and environmental objects you can use to jump off of, climb on, tear down, etc. It is a combination "capture the flag"/fighter where everyone goes dashing around for powerups and attacks each other to get them to drop their power stones. Once someone collects all the power stones, they go into their super mode and it becomes a game of cat and mouse until the effects wear off and the power stones fly off in random directions. This game is totally fun, totally original, and totally worth buying a Dreamcast if only to play this one game.
