It's not really a matter of poor taste, just unrealistic time management. There are way too many good games out there for me to ever actually play them all. I only played like half a dozen games last year. I bought...more than that.
I have a fairly large Steam catalog, most of which I have never played. However, I'm pretty sure they are almost all good games and I will definitely get around to some of them.
My bookshelf is similar. I've only read roughly half the books I have staring me in the face every day.
But on the plus side, anytime I'm bored, I have a wealth of options!
