There must have been hardly anyone stupid enough to buy many games. It’s probably not even much money to refund.
For Google it's chump change, I'm sure, but I still appreciate it. I bought like two titles on there before realizing it was a doomed effort... meanwhile GeForce Now sees very active improvements and a much bigger library.
This is a company so obviously in love with its incredible success from ages gone by that it thinks we still owe it our brand loyalty. We do not.
(if you didn't know, though, xbox controllers do work great with geforce now)
