I guess I don't understand the concern though, what possible disadvantages are there to a streaming service that's built correctly?
Really? Like...requiring an internet connection to play anything? Has everyone in the
GT Sport subforum forgiven it for being always-online now? It's dumb, no matter how infrequently it comes up. I spend small amounts of time on a recurring basis playing games in places with no internet, with no mobile broadband reception. I'm going to keep doing that.
I don't like paying subscriptions when I can avoid it, period -- it rubs me the wrong way -- and the suggestion of paying a sub to "play whatever games are being offered" is shooting yourself in the foot. I've seen what that looks like with Stadia, PS Now, Games with Gold, PS+, etc. I would not get my money's worth.
Besides, I
want to spend $60+ on a game, to go out of my way to support developers like Monolith Soft, because making games on that level is expensive and niche games on that level are enormous labors of love. I'm not looking to cut back, because gaming is such an affordable form of entertainment. All by themselves,
Xenoblade X and
Xenoblade 2 each made the Wii U and Switch an investment of less than $1 per hour. To me it's robbery to demand better.
Indie games have almost completely replaced third-party multiplats in my gaming diet, and not all my favorite ones are household names. I also play games that are older than online services that have shut down, and driving/racing games with expired licensing.
Another Metroid 2 Remake is superb;
Mega Maker;
Super Mario Crossover...I've only scratched the surface there. There's so much out there I don't even know.
PC gaming -- mods, unofficial mods, skins, all that. Grassroots development and open source collaboration -- this is one main thing I had in mind in my last post. A future of streaming games isn't anywhere in the picture at all!
And finally, yes -- internet speed. Bandwidth is bandwidth. Ping is ping. I am almost as sensitive to latency as the fighting game community (that's not just an uphill battle for streaming, it's the face of a cliff). I mostly play games designed to have tight controls, not sludge like walking around in Assassin's Creed or RDR2. I'm not surprised if people didn't really notice latency playing AC on Stadia, because it's built-in.
TL;DR -- This is a lot of words to have to explain: it isn't for me, or for a lot of people, for pretty plain reasons, and
the future you describe is not gonna happen whether you like it or not. To each their own. I'm sure you'll love it.
