Made me realize they don't understand GFN at all.

This is Neocore who developed Warhammer 40k Inquisitor and The Incredible Adventures of Van Helsing. Van Helsing has been offline for almost a year and the Inquisitor Prophecy launcher is offline (you can still play all the content through the Martyr launcher). I reached out to their support on Discord.

They first responded with "you can't play unsupported games on GeForce Now." Well, yeah, it's supported. Then they said "because it no longer supports the online mode you won't have it on GFN." Obviously BS. Then they went to "well it used to be supported but isn't anymore. We'll see if we can get them to update the listing to make this clearer." I explained that it's supported because they opted in - it's just broken. Then they finally said they won't be able to get anyone to look at it because the game is not supported anymore.

It's baffling that this is the response from a company that has opted all their games into the service.
