Terra Firma

Neat little simulation that produces shockingly realistic terrain, but not really much to do. Feels more like an educational tool that would be used in classrooms than a true game. Other uses beyond education I think could be using it to make more realistic maps/areas for DnD campaigns or using the simulation as a reference image when drawing wide establishment shots of a landscape in an animated film project.

very good

Pretty good for being free and worked on for a long time. Milo Rossi's Antarctic Pyramid conspiracy debunking video informed me of the second game, but due to a big vet bill I couldn't purchase it and instead opted for the free original. Don't expect to save your worlds or ever see them again. The introduction is a little late and only explains things after you have started building a world, not when you start. I had a lot of fun setting up my world on 2,000 years while I ate dinner, and coming back to see how dramatically the landscape had changed in only ~30 minutes.
