I always enjoyed playing video games, but my parents have always been very strict about how many games I bought and how much I spent. Since they were my only source of income growing up, I was forced to live under their rules. They always said they wouldn't buy me any new games until I had finished the one I was currently working on. Carrying that mentality to the present, I refuse to buy any other games unless I finish the most recent one I've bought.
How about the rest of you? Do you buy a number games all at once and play them one at a time? Or do you buy your games one at a time, like me? I know a few people who have a lot of games in their libraries, but haven't actually finished more than 2/3 of their collection.
