Chrono Trigger on the SNES. Amazing story, excellent animations by the guy who created Dragonball Z, masterful music, likable characters, first game to ever include New Game+ mode, multiple endings that depend on the choices you make in game, and much much more i'm probably forgetting. There have been few games that have captured me the same way this game has. I still religiously play it once a year to boot. Unfortunately, they don't make them like they used to anymore. Though I have hopes for The Witcher 3.
