I don’t get the concept of buying a console or using a service that streams the games, meaning I cannot play them offline (I play games mostly in Transit, buses, subways, etc that don’t have wifi) - and meaning I ultimately don’t own the games I buy, and when Google predictably shuts this service down as it is notorious for doing, I don’t have anything to show for my investment? I would never buy a serious console game on anything but hard media. In a couple years, all the money people spent on games for Stadia will literally have been completely wasted - and my Sega Genesis I got when I was six, and the games I paid for 20 years ago will probably still work (I’ll admit bitrot is a concern, but that’s a hugely different issue), along with my PS5 or whatever I’m using at that point. This is a zero-value, long-term net-loss concept for me. It boggles the mind.
