I am moving Gamer+ to a new server and installing a more modern software, Calckey. Calckey is federated so you will be able to share and read content across the Fediverse with people using Mastodon, Friendica, Peertube, etc.
The current Gamer+ site will remain available at archive.gamerplus.org so we won't lose any content. During the transition there will be occasional downtime with a plain text screen or even errors.
I will send another email when the new Gamer+ is ready.
For your public domain AI Art fix I've got Tavern Row for your next game.
