The second part of the trilogy, Mass Effect 2 sees the return of protagonist Commander Shepard in a huge role playing action space opera.
It's well designed for new players, as well as people who completed the first installment and still have their saved game - their Shepard will be the same one they played before. The combat part of the game is much improved, making the whole experience much better.
Mass Effect 2 looks incredible, with excellent facial modeling and incredibly dramatic locations and landscapes. The massive storyline puts the fate of the galaxy in you and your team's hands, meaning decisions you make in the game feel very important, and the emotional impact is very big.
It's not a humorous game, but the scale, visuals and drama make up for that. Mass Effect 2 is a huge improvement on an already fantastic game, and means anticipation for Mass Effect 3 will be huge.
Any science fiction and RPG gamer will love Mass Effect 2, one of the best games of its kind ever made.
