I originally bought it to play DnD with friends. However, I got so distracted with tinkering around in it that I spent more time making battlemaps and utilities than I ever did actually playing a campaign.
I’m not sure about solo games specifically for it, I’m sorry! Have you had a look through the workshop for things?
Meanwhile the original game is stuck with rockpox for 8 more months.
I do not enjoy the rockpox.
