I’m not sure if this fits as an idea for a further enhancement, but…I used to play Forsaken on the PC. It’s Descent type game and I loved it. I recently discovered that the source code was released a few years ago and it’s been compiled for some flavours of Linux (https://github.com/ForsakenX/forsaken/wiki/Download-and-installation). It runs from the download on Lubuntu but I can’t get it to work on anything else so far. I followed the included instructions to compile it but this is all new to me and it didn’t work. It’s been done for the Pandora (handheld Linux computer/console). Would be a superb game to have on directly ported to the Pi and especially Retropie.
