Bioware makes excellent RPG, this is sure! After Knight Of The Old Republic here is a similar game with a brand new, exciting setting! The story is great with many surprises along the way, the game itself seems most like a movie and a great one with wise camera positions to capture the atmosphere of the moment. Very good sound effects, interface and musics. The exploring and combat parts with the Mako AFV are a great idea. there is even some space for some quite hot romantic moments, yup!
The only drawback is the limit to three men in you combat team.
