One of the best multiplayer games to ever grace a system
I have yet to see one, just as i can't see anyone make a good party game like Nintendo with Mario Party. That is, except for Power Stone 2.
The game is all offense and never anything close to defense except running away and even if you do, you'll barely get far since the game encourages offense too. Basically the game greatly encourages only one to survive as you have to escape from giant boulders, other enemies, and weapons everywhere.
The game is great, too great in the sense that you want more. More meaning more levels and boss battles, everything so you can play a bit longer.
Everything else it gives you plenty of. Characters and especially weapons, to the point of making your own weapons and you can make a whole arsenal worth.
If you're tired of Smash Bros. go for Power Stone 2, since as close as youll get for a 3D Smash Bros.
