When you confuse things from The Witcher with other games. For exampleWhile playing Monster Hunter Freedom 2, I'm hunting and there's a bunch of prey(raptors) around and I'm using a great sword wishing.. Where's Group Mode. Not long after you're hunting large game ironically enough a Wyvern and you drink a potion or two before every battle and wish you wonder why your sword isn't doing anything.When you walk out of your house and you have a lot of plants namely herbs and mint and yes even nightshade and you begin wondering what could you make. When drinking iced tea with mint you start thinking its like Blizzard.When your Ice cream creates Blizzard like affects and your head hurts. When you spent 14hours or so playing the game or thinking/reading/ or on forums about the game while you're awake and when you sleep you have dreams about it. When you feel comforted knowing you have multiple swords around your bedroom just incase a kikimori or any monster decides to pay a visitYou know you're playing too much when you start wishing that you lived in that world and were a Witcher solely due to you have a good sex life, get cards after sex, get paid to kill monsters, killing said monsters.And you look badass while doing it.You know you played too much when you are already planning on spending more money than what is realistic wanting exact replicas of the swords, medallion and the dagger from the game. As well as upgrading your computer to a level where its overkill and saying to yourself. its ok I only need to kill a wyvern or two and I have enough orens.Last one occured to me earlier today and I sat back and was like... ok... this is bad.
