Crono Trigger.Definitely.
The story is pretty, it shows the power of fate over our lives, which i mostly concur.Even its side adventures, like saving Lucca's mother, are very beautiful, along with its extraordinary soundtrack.The game has so many touching moments, like when Marle and her father understand each other, when frog goes to Crono's house to get the doll, Lavos first appearence and that apocalypse aura...Very well made game, made with passion, that's why that game will never die.
