Some games are just so good (at least to you, if nothing else) that you just KNOW you'll come back and play it again. And again. And again. And so on. So, what games do you keep?
For me, it's LittlBigPlanet 2, Batman: Arkham City, Dark Void, and Valkyria Chronicles (all on PS3), Muramasa: The Demon Blade, The Legend of Zelda: Skyward Sword, and Zack and Wiki: Quest for Barabaros' Treasure (all on the Wii), and Tales of the Abyss, Final Fantasy Tactics A2: Grimoire of the Rift, Dragon Quest Heroes: Rocket Slime, and Solatorobo: Red the Hunter (Tales on 3DS, all others on DS).
I must confess, I did sell Dark Void, FFTA2, and TLOZ: SS, but I bought them again when I started missing them.
