I bought the founder's edition Stadia hardware and I'm thrilled with what I got out of it, personally. I got a free game system for years since they are giving everyone refunds. Played several AAA games I had no access to otherwise. Still going to have the, now free, Chromecast Ultra 4k with ethernet cable power adapter afterward too. It works fine even if I don't pair Stadia controllers with it.
This Ubisoft initiative to transfer licenses to PC is actually worthless to me since my PC doesn't have a GPU capable of playing games anyway and I have no intention to buy one.
