I blogged a while back about my great love for BioWare's sci-fi RPG epic Mass Effect. The gaming community has long known that the game was the first in a planned trilogy, but over the weekend the first official glimpse of Mass Effect 2 was revealed with a teaser trailer. The video is certainly a teaser, and it has Mass Effect fans like me in a tizzy over the fate of the Commander Shepherd we created and shaped in the first game. The developers at BioWare are telling Xbox 360 owners to hang onto their saved games from the original Mass Effect for use with the sequel, so perhaps the trailer isn't quite what it seems. Anyway, have a look - and if you haven't played the first Mass Effect, really, what are you waiting for?
