> Access to Steam's library for a fixed monthly price would be huge. Actually I'm surprised Steam/Valve isn't offering that yet, it'd be huge, and for their new consoles it would be a perfect fit.

As a consumer, I really hope they never do that. I hate subscriptions and strongly prefer to just buy games. Once there's a subscription option, I would imagine the great sales would get significanty watered down. If you're a game seller and you can get that sweet sweet recurring revenue, it's too strong a temptation. We've seen that story play out time and time again in SaaS (and even some desktop applications now).
