Xbox Cloud Gaming, unfortunately, it's far from ideal. For several games, lag kills the experience. And I'm not talking fast paced FPS. Even platformers can feel weird or unplayable when you add latency.
Assuming the infrastructure over time can support it, I see cloud gaming succeeding, but it only works well if the circumstances are perfect.
Is your experience for xcloud or all the cloud gaming platforms in general?
Even? Super Mario Brothers lets me know very quickly if the lag on my set-up is anything other than quite low, because I'll fall down every damn bottomless pit on the map.
