The SNES Mario when I was a kid :C...A person rescuing a captive princess from harm was quite embedded into me since my relatives used to tell me fairy-tales (ugh) quite a lot. Other than that, I never found any other game touching as I mostly play action or open-world games.
EDIT : Yay, 200th post and a Psychic now :3!
EDIT 2 : Also Adventure Quest Worlds! In that game, I had made so many friends and had so much fun grouping together, chatting, fighting, farming equipments etc and I was deeply disheartened when Artix Entertainment perma-banned my account because a wimpy little hacker hacked into my account, The Dragonking and they wouldn't believe me :/.
