I am by no means a nerdy guy but do like to play shooters at night when i have nothing better to do. I am into Shooters so i am getting Call of Duty 4 for christmas. Now would Mass Effect be a good game even though i dislikeall otherrpg(WoW, Oblivion, or anything of the sort) without even playing them(they fit into my nerdy category but thats just me). The game just looks different and i want to get it. do you have to like rpgs or sci/fi(stuff like star trek) to actually like this game.
