Thanks for the comments TW, again, much appreciated.
Understand on the wait times. The same thing irritates me with Netflix also. I know that Netflix absolutely does not ship or process returned discs on the weekends or holidays. That means if they would have received something you shipped back on Saturday, it will be Monday before they officially receive it, and then ship you your next choice. Those built in hold times are part of what Netflix is trying to profit on.
Netflix has also been caught (thanks to someone with a lot of time on their hands to analyze their practices) fixing their selections so that low profit customers (customers that rent a lot from them in a month without being on one of the more expensive many discs at a time out plan) will be at the bottom of the rental que, and be stuck with waits for items. I forget the exact analysis, but I had observed the same things myself (and continue to observe them). If you rent a lot, no matter how much you rush to ship things back quickly so you could get something else in the same week, the odds are stacked against you being able to get any of the more popular selections. You could get more older selections (maybe), or be stuck with lots of films in your que you'd never get.
Anyway, I understand where you are coming from on being stuck with a small selection of games. I hate buying a bunch of games when I know I'll never play them through, but I also hate not having choices. I like to have a few different games to sit and choose from when I fire up the gaming system. Not a ton, but enough that I could choose say auto racing (like PGR3 or Ridge Racer), Baseball, Football (like Madden) and perhaps Hockey or Hoops. Oh, and a good First Person Shooter (FPS) like SOCOM, Call of Duty or similar.
