It is such a confusing proposition to buy. I got a discount offer for the Stadia (£60) but I couldn't find an official list of what games are available, or how much they cost! Then I found out that if I wanted the 4K streaming it'd be an extra tenner a month! At which point it is cheaper to buy a 2nd hand PS4. And, that way, I can buy 2nd hand games if I want.
