Tintin and the Temple of the Sun, for the Gameboy (the original). I was 7 at the time, and got pretty much all next versions of the gameboy up to the Advance SP and a ton of games. My first PC gaming experience was Tomb Raider if I recall correctly, but back then it scared the shit out of me so I never got very far with it (I did watch my dad play though, back before he stopped gaming).
