I also think there’s a genuine drop in satisfaction when people are presented with more options. I limit myself and only buy new-ish games when I feel like I’ve extracted as much enjoyment out of the last one I bought as I can. I think this helps a lot.
Because what I see a lot of people doing is jumping to the game-of-the-week and then getting numb and saying “there’s no good games” even as they continue to buy new ones every week.
