User Rating: 9.5 | Mass Effect X360
Mass Effect is one of the greatest games on the Xbox 360, combining innovative roleplaying with a solid shooting system. The games begins with a bang, you are on your ship when a distress call is received. Needless to say, by the first hour you should have gotten more done and had more fun then if you played the average game through to the finish. If you thought The Elder Scrolls IV was the epitome of role playing games, you were wrong. Everything about this game is fluid and well thought out. The voice acting and facial animations are the best I have ever seen, and unlike Oblivion, the characters actually do things when they talk to you instead of standing and looking strait into your eyes. The only bad thing I would have to say about Mass Effect is that when it comes to the side missions, the architecture and the planets are all the same. That one small nagging detail should not stop you from buying Mass Effect, the greatest game on the Xbox 360.
