Right now, it is either Sin of a Solar Empire or Homeworld.
But I am not playing the actual games, but the "modules" for Star Wars and Star Trek. I am such a geek, I go in to the source files and tweak the strengths of ships, total number of ships or capital ships, etc.

Any of the atelier games, Sims, persona 5, stardew valley, holy potatoes weapon shop, rouge legacy, and never winter. They are my favourites at the moment
