Codex Gamicus
Free* game(s) on Epic Games

Obduction is a first-person adventure game developed and published by Cyan, Inc., the creators of the Myst series of video games. It is, first and foremost, a puzzle-solving game, though a rich story is told through both the puzzles and the environment. You play the game as yourself, rather than taking on the role of an established character. Upon being abducted by a strange flying "seed", you explore your new environment in an attempt to learn more about the nature of your abduction and how you might return home.

Offworld Trading Company.webp

Offworld Trading Company is an economic real-time strategy game developed by Mohawk Games and published by Stardock Entertainment. In the game, money, not firepower, is the player's weapon. Players must stake their claims to resources and wrest any advantage they can buying and selling on the real-time marketplace – but greasing some palms on the black market for a timely pirate raid on a rival's supply chain can make all the difference.
