So I caved in and got Mass Effect...
I was kind of confused because the first few hours were linear and I always thought it was an open world game. Now I finally got to the point where it opens up.
Enjoying so far? I for one am addicted. ME2 feels kinda weird right now, prolly cuz i did 3 playthroughs in a row with the 1st one and got way too used to it.
