I'm not much of a gamer, but I've always been interested in playing Red Dead Redemption 2. However, I neither had a console nor a PC with a decent enough graphics card.
This spring, I picked up a Google TV with Chromecast, and realized I could pair any bluetooth device with it. I bought a cheapo PS4-like controller off of Amazon, saw that RDR2 was on sale on Stadia, and gave it a shot.
I have to say, the experience was quite pleasing. No need for an expensive/out-of-stock graphics card. No need for a dedicated console. If feels like a great solution for a casual gamer. Overall, I've been impressed with the experience, and haven't experienced any lag or game stutters. Heck, it even plays Cyberpunk smoothly!
Stadia definitely lacks in terms of marketing and game library, but I feel like it's a concept that works.
