So to, for example, play Steamworld Dig on Stadia I need to...
1) Buy the game at full price or occasionally at a discounted price during sales. Or I guess get it "free" when its offered if I'm paying the Pro subscription.
2) Have online access the entire time I'm playing
3) Have a good enough internet connection that the game plays kinda mostly how its supposed to with some occasionally latency-induced lag.
4) Ensure that the GBs and GBs of bandwidth I use streaming the game doesn't make me go over my data cap.
5) Have a good enough computer to properly play the compressed, encoded video stream in real-time.
6) Hope that the service remains so that I don't eventually lose access to the game entirely.
On the other hand, to play Steamworld Dig literally anywhere else, I need to
1) Buy the game at full price or occasionally at a discounted price during sales
2) Download something like 300MB of data exactly once.
3) ...that's it. There is no step 3. This game can run on a toaster.
Someone tell me precisely what the value proposition is for this service outside of the highest of high-end games that are just simply unplayable on all but the most cutting-edge of gaming hardware? The number of which I can count on one hand by the way.
