with a short description.

each suggestion will be graded with 25 pts- a-graded

TEKKEN TAG (not tekken3 or tekken2 or tekken 4)
- fighting . nice grafix and not boring for a multiplayer.

Tenchu: Wrath of Heaven

This has a nice two-player version which allows the two players to compete head to head or cooperate in missions and the single player game isnt too shabby either.

The graphics are very good, and the game engine is excellent. There is an emphasis on stealth (duh, you play ninja ;)) in combat. It has excellent replay value for both one and two players.

What kinds of games are you looking for?
