I wrote a message to Genius Games recently:
Good day, Genius Games person.
Which games, if any, do you have that incorporate a Solo Mode/Variant (1-x Players), or will, in the foreseeable future?
Genotype and Tesla vs. Edison (with the expansion) have official solo modes. Our next 2 Kickstarters (First in Flight and Cellulose) will almost certainly both have them (I’ve been running the solo mode for FiF today). Cytosis, Ecosystem, and Origin of Species have unofficial modes by Ricky Royal. You can join our Discord if you’re interesting in trying out new solo modes while we’re still in development.
