Final Fantasy 6 -- Music from Nobuo Uematsu. Opera scene. Steampunk fantasy. Autocrossbow. A world that is literally destroyed and reformed. Finding all of your comrades. A 20-minute ending.
Just Cause 2 -- Because it never gets old trying to land your plane on a small island . . . or on top of an airship . . . or jumping out of your plane at 30,000 feet so you can stand on top of your plane. Or dragging things around with the grappling hook. Or finding all of the Easter Eggs.
