Since this console generation is coming to a close, I think it is safe to write up a summery of some of the most important games this generation. And trust e there is alot that could make it onto this list. But in the end, only view could have the huge revolutionary impact on the gaming industry.
Game 1: Elder Scrolls IV: Oblivion
Something about this game was just awesome. Yoou had a massive world, tones of quests to do, a well written story and a good soundtrack. But not only that, Oblivion was as massive as an MMO but in a single-player format. It really shaped console westren role playing games and sandbox games in general. Now with the release of Skyrim, not may people still play Oblivion (Atleast I don't at all) But it is safe to say that because of the success of Oblivion, many good RPG's may not have had many break throughs.
