The list is endless for me, I'll play a game to death, then discard it like a used condom. I'm rather fickle. The main offenders are many of the above mentioned, and then some.
Have to agree here..mspencer82 said:-The Sims. There was something about carefully crafting a house, creating the model family to live in it, and playing through until they had become moderately wealthy with an expanded "perfect home" and all of the expensive furniture that really became obsessive. Or maybe it was locking the father of said perfect family in a small room with no door, no food, no bed, and no toilet. Don't judge me, you know you've done it.
