There is a solution! There are places out there that let you pay a little money and play a game for a little while. Some of them even deliver the games right to you. Rentals can be a lifesaver for those of us who are strapped for cash. But they don't really let you take your time with a game, and they definitely do nothing for the collector instinct.
Do you ever take advantage of rentals? Or do you find the idea of playing scratched discs that have been who knows where too distasteful to consider?
