When I found the first Mass Effect on PC, I hadn't actually followed up, or really seen much about the game at all, no trailers at all, I bought it.
it was an epic blend of Sci-fi action and RPG, and this game Is shaping up to be incredible, the choices you made from the first game will carry over into the second, really making you feel like you were in “your” own world.
The plot is looking really deep, and from what I've heard of the soundtrack, it's awesome.
If you have played the first one, get this, if you haven't, get the first one and then this one! (PS Mighty Ape has the best prices)
