At a glance it seems to be mostly different people that have replied in this and your thread, but I'm still firmly against any subscription service on Steam.
Totally accurate. I wasn't suggesting a hive mind or anything, and my proposal was slightly different in that it was presented more like GwG and Instant Game Library as opposed to the similar but different strategy employed by EA. I just pointed it out because I'm curious if this sort of thing is becoming more palatable as time goes on and more people have experience with these types of long term rental subscription services.
I still think my suggestion of allowing people a handful of titles out of a (rotating?) pool would better suit the diversity of PC gaming though. There is just too wide a spectrum of taste and genres on PC to cater to without offering at least a few options for players to choose between. It seems like that would also allow them to keep costs down too since they wouldn't be having to maintain licensing at the same volume for a huge number of titles when certain ones would never be played by most players.
I mean even on consoles tastes range enough that many people are often unsatisfied by the titles offered or the rate they are added.
