I had to stop buying stuff (nearly all things, in all categories, not just video games) years ago because they were outside of my budget. I can treat myself every now and then, but that's it.
I always squeezed fun out of my games, but I've spent a lot more time with some Famicom/NES titles over the past few years than I normally would have and I am better for it.
Of course, if I was rich, I wouldn't be so busy at work, and I'd have more time for games.
