It's an aggregator for cloud gaming, so you can find which platforms stream your game.
From the platform's own listings.
You're probably out of luck.
Drat. This site is designed to get its data automatically without human intervention, so that it doesn't go stale if I get busy. But unfortunately the platforms' own feeds are sometimes missing titles or contain mispellings, etc. Some platforms — Bosteroid in particular — may run games outside of their listed catalogue.
I'm sure there are. See above. My design is for a self-maintaining database that is big-picture accurate rather than razor-focused on every title.
Right now I'm focusing on the big platforms. If you think another platform is ready for prime time, let me know.
Every Friday. Geforce Now updates their list every Thursday; the other platforms update a little less frequently.
Generally, yes, but xCloud and Luna are subscription-based. Read up on them.
It can be! You really need a good internet connection and a solid link between your device and your router. Good connections can make for an amazing and inexpensive experience. If your internet is bad, you'll hate cloud gaming.
It probably comes down to what you want to play. The platforms' technology are broadly similar. IMO, xCloud has a great user experience; GFGeforce NowN can go above 1080p and can have slightly superior streaming image quality and less latency. Geforce Now and xCloud likely offer the best in-game quality settings. xCloud continues to have latency problems on the web.
GFN connects you to a PC using your logins to PC stores like Steam, so games that are already out on PC can be added to GFN's platform pretty easily. Not all publishers are cool with it though, so you'll see lots of AAA titles missing.
