When I was 7 my step-dad took me to his friend/drug dealers house and he passed out on the couch while his friend railed a line of cocaine before loading up a bootleg copy of Oblivion for me. I played a pyromancer pirate. It was fun.
I live in the Philippines so I didn't have much memories regarding playing videogames when I was a child. The best I can say is Tekken 5. I main Asuka Kazama.
