Eh, a person who plays a game perfectly is either cheating, or playing on easy mode (granted, some games on easy are still a pita). However, it can truly be said that you've never truly won a game if you haven't lost a few times . . . have to figure how and how not to apply the game's rules. A real/true gamer is merely someone who spends a good deal of free time playing games, regardless of how, and mainly due to love of the concepts/genres. Personally, I'd hand him the game and say, "Prove it." Then keep tally of how many times he dies/doesn't do something "perfectly." Keep an eye on him though, he seems to be a developing troll. Course, if he gets on your nerves, you could always tell him to go back and rot under his bridge (granted, that may be a bit too harsh, but you get the idea . . . I hope).
