I've played the first Mass Effect and loved it! But there were a few complaints, such as the annoying Mako vehicle, and some of the boring leveling up aspects. ME2 takes everything you loved about ME1 and fixes everything you hated about it. The fighting is better, the character development is better, the story is more engaging, and the game is just a more polished version.
One word of advice, although the game is still amazing to play by itself, I urge you to play ME1 before getting into ME2. It is so very cool to see all the decisions made in ME1 carry over into the sequel, however small they may have been. Considering ME1 is so cheap right now, you have no excuse not to!
