I'm not sure why exactly, but I've always felt compelled to keep buying games. Some I obviously want to play, some I just wanted to help out the developers, some were a simple case of the fear of missing out. In general I always wanted to have certainty that whatever my mood there would always multiple choices available in my library. I'd say a good 20% of the games in my library are trash usually picked up as part of a bundle, but even counting the just the other 80% I'll be lucky to ever get to even a quarter of them in my lifetime.
