My favorite 360 game would probably be Skyrim or Fallout: New Vegas. Both great games made by the amazing Bethesda Studios. Mostly any game made by them is just an amazing game and would recommend to try them out if your a RPG fan. I'm just waiting for a new Bethesda game to be announced like Fallout 4 or a new Elder Scrolls game or maybe even a new series.
