UPDATE ON GAMESESSIONS SERVICE
24 November 2020
Dear GameSessions Customers,
We are sorry to inform you that we have decided to discontinue further plans for a relaunch of the Gamesessions service.
The current client will remain supported until December 30th 2020 - after which there will be no more updates or support.
The games you have bought or unlocked through the platform are of course still playable through the relevant service where the gamekey was registered - in most cases with the Steam game platform.
Thanks for your support and dedication through the years!
Nothing on what will happen with the games that were given out for free after a 5 minutes of playing. They can't function without the launcher, and it seems that they do try to connect to a server so, if they shut down everything on December 30th, then we may lose the ability to play those games. I hope they'll push a last update to remove their bloatware and allow us to keep the games forever, but I'm not holding my breath...
