You know you've played Oblivion for too long if...
You can tell Viper's Bugloss from Nightshade at a distance, but you can't tell an oak from a hickory in real life.
You can identify more plants in Cyrodiil than you can on Earth.
You look for the "Fast Travel" option when stuck in traffic.
You go deer hunting and try to outrun them.
You look for shrines/ruins/forts when going on a walk.
You have an escape plan in case of a Daedric invasion.
You've designed a real house based on one from the game.
You think about casting a "charm" spell when asking for a raise.
So what are some of your "ifs"?
