I have. I used Geforce now, stadia, luna. I bought the hardware controllers. I've tried all of these platforms across all different form factors (pcs, laptop, ipads, iphones, android, LG television). I've signed up for individual games, game publisher channels UBISoft+. I invest millions of dollars into companies and my thesis is product driven. All of this is research I conduct myself, for myself. That isn't to say these services have gotten better since I last tested (Geforce i probably tested in November). From what I remember, it was a PC virtual machine with a queue system for availability. It wasn't "magic". Stadia is magic. Luna is somewhere in between.
