Here's some confirmation of what most of us already knew: a study by Frank N. Magid Associates shows that renting is bad for game sales. In particular, check out these two findings:

1. Nearly 50% of all console game renters didn't purchase a single game they rented last year.
2. Only 9% of renters bought 11% or more of the games they rented.

In short: if you rent a game, you don't buy it. But who ever bought that whole "try before you buy" argument, anyway? Though I will admit to keeping a few games from my monthly mail rental service of choice.
