Nope; no interest.
For multiple reasons
1.) I don't like the idea of paying for something I don't own. I'm still very much a "I pay for it because I want to keep it and have it be mine" type of guy and streaming is the enemy of that. I like having my little collection of games from multiple systems on the shelf.
2.) Until they can show me a game that needs input precision like a fighting game being played competently over streaming then they'll never have me. Lag in online fighting games is already bad enough at times, but the added lag that will come from streaming in video, sound and relaying inputs just sounds terrible to me. Fighting games need precise timing and I don't see streaming being competent enough to handle it to the point where it's not noticeable. Same for Rhythm games. You need precise timing for games like these and I don't think streaming will do them justice. So no thank you.
3.) Rely's entirely on a net connection that is prone to go down at any moment. Say I'm playing Sekiro; and I'm up to the final boss..but my net drops out randomly due to maintenance on my ISP's behalf. I'm like one or two blows away from beating the game. Oh wait, sorry, your connection dropped out...please wait until you get a net connection back. Yeah, no, fuck that. Fuck that. My PS4 would keep going even if the net connection dropped out so tell me? Why would I want something that could drop out the one moment my net cuts out during maintenance?
4.) Buffering...I don't trust this thing not to buffer, drops frame or introduce lag of some type. Again, no thank you.
Nothing about streaming games appeals to me to be honest. Sure the tech is cool but there's just so much bullcrap with both input lag, poor connections = poor video quality full of macroblocking and such; too much of a reliance on a net connection that could fail you at any moment.
Yeah, it just doesn't appeal to me at all.
