Whoa jeez....
The last thing I rented was Sunshine over 7 years ago. (However, I did rent Skate 2 and beat it in a couple days after it'd been out for a bit.)
I remember begging my mother to take me to all the rental stores and I remember calling around to see who had Sunshine (naturally, it was the farthest one away from us), but I got it and loved it. I kept it for 8 days (renting it for 5). I'm really, really bad about getting games back on time... but that was a looooooong time ago. I don't ever plan on renting anything ever again. Waste of money to me, as far as I'm concerned. With Xbox LIVE letting you download demos of tons of games, it has totally killed any need for me to go rent a game before purchasing. For the Wii, the only thing I buy for it is Mario and/or Mario-related stuff (and I'll never buy another Guitar Hero game on Wii for the rest of my life... huge mistake), so I know I'm not gonna need to rent NSMB Wii before I decide to buy it, for example.
With lots of good game dying out my collection of games has gotten progressively smaller from console to console. I have like 45 N64 games, around 12 GCN games, and my Wii has 4 disc-based games (not including Wii Sports) with a bunch of VC and Wiiware stuff. My 360, however, is progressively getting more games and downloadable games on it. The last thing I dusted my Wii off to play was Super C after I downloaded it (and a couple levels of Galaxy).
