The long wait for Mass Effect is about to come to an end.  Microsoft has announced that Bioware‘s highly anticipated sci-fi RPG will release on November 20th in North America, exclusively for the Xbox 360.  The game, which incorporates GRAW-style action with role-playing elements familiar to anyone who played Knights of the Old Republic, has been one of the 360’s most-wanted games since the day it was unveiled.  Until now, it had been pegged with the precarious and open-to-delay release time frame of “November.”  So the news that the game will officially be here in just a few short months is definite cause for celebration.
