Pokemon Mystery Dungeon: Explores of Sky for me. Currently one of my favorite video games of all time. Great story (and the post-game's story arc and special episodes for Bidoof and Grovyle was incredible was well), great character roster, the sidequests are unique and fun, and the free-roam environment was a ton of fun as well. t's the only one that's constantly made me cry (or close to it) since I've been playing it (over and over again) at 10 years old. (I'm 16 now.)
