Here are references to get you into the genre:
Games – Video Only
All Games – Roleplaying Too
This list includes Space: 1899. The original game is out of print, but I took part in a Kickstarter for the new version. Contact the project runners to find out if you can get it from them.
This is far from a complete list. I’ll likely update it over time. This will, at least, get you started.
