4 stars: As long as you got 100 up/2-4mb down Internet, your ISP doesn't variably throttle you, & your local network isn't loaded down, you'll never know you're not on an ultra high-end PC & not being streamed through the Internet. 1 star off for Dualshock 4 compatibility/support being null/void & unusable/unconfigurable. Mouse/Keyboard, Xbox One/360, & several other USB/BT gamepads work fine.
4 stars: Great idea if you're close to a server, not so great if you're not. I leave my server on auto but it always tells my that I'm too far from the server. Not really a problem until the latency spikes high and the game becomes so pixelated it's unplayable. Other than that it runs smooth and looks great. Waiting for them to add Fallout games to the list.
3 stars: It's a work in progress. It's resyncing my Stadia games. I was able to play Far cry new dawn and Rainbow six (without losing 1 year's worth of progress). I'm using a Chromebook on ARM and spotty wifi connection and still getting very high quality almost lag free gamestream. But I'm not playing at 4k or 120fps on a portable 13
2 stars: Exceptionally great idea that just doesn't work well on Android. Audio constantly stutters and it frequently crashes or disconnects. Even with a 5g connection which is pretty disappointing. If your willing to play with audio off and bear the interruptions you can power through playing a game but it's not nearly as enjoyable an experience as a dedicated system.
