Interesting for you to assume that since I literally mention sales (I don’t buy games outside of sales at this point.) No, in fact, I just feel time is more of a factor than anything else. I don’t play the 40+ hour games anymore because they typically aren’t interesting or worth my time.
I find that when the winter sale rolls around and something I thought I’d like is in it I find out that I really don’t want it anymore. That I would be happier with something else. So instead of increasing my wishlist to 1000+, I am really stingy and realize that I will just pick up whatever looks good during the sale rather than looking at a huge list of games that typically no longer interests me.
