I used to be a gamer, playing hours competing online every day around the Diablo 2/Warcraft 3 times but have since largely lost interest in it as a hobby.
These days I'm more interested in killing a half hour here and there, sometimes a rainy sunday afternoon. Almost exlusively more narative driven or not very mechanically demanding single player, often turn based games and couch coop.
I'm pretty happy with my Switch as the only gaming device, but I find it a hassle to look up which games are out, check reviews to see if their worth buying, maybe wait for a discount and wait for download. Then feeling bad for not having finished most.
So a service which I can just pull up when I feel like it, and click on a random game and immediately start playing for a while then either move on or come back is very attractive to me, and unlike other streaming services I don't care much about owning the product.
That said, I have never tried cloud gaming service, but for the convenience I'd be willing to make quite some concessions. E.g. keeping the Switch for the 2-3 fast paced party games I play.
This has happened to me...
I don't get this statement. Don't you need to purchase an Amazon Controller for $50 and if you want a good SoC and 4K capability you'll also need to purchase a Fire Stick 4K at about $50 which brings the total to $100.
As for Stadia - there's no need to purchase a Stadia controller or Chromecast 4K. I've used an Xbox controller and Chrome to play just fine.
That said, I think there's a tendency to pooh-pooh the "gamer" concerns about streaming far too much in the rush to declare that the state of technology couldn't possibly be an obstacle to launching a product. Just from this year two of the most popular games with non-gamer audiences were a samurai adventure that sells itself on its HDR visuals that wouldn't look so great compressed (Ghost of Tsushima) and a party game where you wouldn't need to be a stereotypical FPS gamer to notice and be infuriated by relatively small amounts of input lag (Fall Guys). Yes, people who don't play games all the time will be less demanding, but don't forget we're still talking about them playing games.
