I have adamantly defended GFN because of it's performance, and the fact I've had like a year free.
Having said that, GFN is doomed unless they come up with something quick. This Opt-in strategy they have going screws customers. Let someone buy a game just to have it taken away 2 days later, they will never use the platform again and will tell their friends to stay away. It's anti-consumerism and frankly just bullshit.
The problem is that some very big money liked Nvidias idea and now they want them out of the way. I just don't see how Nvidia can win without a drastic change in the way they can get you the product with a guarantee it won't be useless.
I vote for bringing back rentals! Let us rent games for $5/day, $10/week, $20/month or whatever works. I think it would be huge.
