- Cataclysm DDA Is THE open world zombie survival experience. So long as you like obtuse roguelikes with nearly no graphics. - Although Im obviously biased what with being a dev and all. 
- Did you guys tried Endless sky? Awesome game if you love space - And minetest+mineclone2 is pretty good if you want to play minecraft but don’t have a license 
 
- I haven’t seen any incremental games get posted. They aren’t exactly traditional games, but so many of them are open source like Antimatter Dimensions or Synergism. Bitburner is a unique one as an incremental hacking sim, since it relies on actual scripting to grow and automate tasks. 
- Cataclysm: Dark Days Ahead 
- Beyond All Reason - https://www.beyondallreason.info/ - It a grand scale RTS game with robots and insects loosely inspired by Total Annihilation. 
- Veloren
