I swear I'll finish more of them when I get some free time.

Though it certainly is nicer on my wallet to normally grab games on sale.

I was looking at my Steam library and wishlist last night, in anticipation of the upcoming summer sale season (other storefronts have already begun their summer sales), and I was somewhat disappointed in myself. Even though I try to only buy games on sale, I think I'd likely save money overall by only buying (and finishing, if I'm enjoying them) games at full price when I'm ready to play them vs. speculatively buying games on sale.
