Take the basic gameplay and setting ideas of Trials In Tainted Space, strip out that game's utter mess of "too many cooks spoils the soup" until only the best and most consistent writing is left, condense it down to a size that is satisfying rather than overwhelming, and add in a really good main protagonist (by any standard, but especially for an H-game), and you've got MERCANOID.
I'm glad you enjoyed it so much!
The setting as it exists is something cooked up over many years, actually intended to just take place on post-human Earth/'Terra'. But when I got the basic ideas for MERCANOID, I decided it could work in that setting's future, which also allowed me to sprinkle in various references to future (past?) projects down the pipe. ♥
