Signs that you have been playing a game way too long.

You can tell you've been playing games to long when after deciding to stand up to grab a drink or snack and you faceplant onto your floor, hopefully you've have a dog to come make you feel better by coming and over and staring at with expression of wtf

You know when you've played Metriod Prime too much if after you complete the game you spend the next week staring at things trying to scan them. (Actually happened to me...)

You know when you've played Starcraft 2 too much when your answer to everything becomes "Spawn more Overlords" (Again happened to me... Damn zergs needing more Overlords D

You know when you've played Fallout 3 too much when you look through every box you see just incase there is a bottle of Nuka-Cola inside. (I really want a Nuka-Cola... My bottle of Pepsi isn't quenching that thirst)

You know when you've played Team Fortress 2 too much when you wear every hat you own at the same time and call people who aren't wearing hats "Poor and Irish" (That got me into trouble with my Irish friends...)
