Did you guys tried Endless sky? Awesome game if you love space
Simutrans. It’s old but really good. It’s really easy to lose 10h or so in it before you notice the time.
If you like RTS games similar to Total Annihilation, you should definitely check out Beyond All Reason, it’s gorgeous and fun: https://www.beyondallreason.info/
This looks really cool. SupCom wasn’t quite the same for me so I’ll have to check this out.
Cataclysm Dark Days Ahead has been mentioned so I’ll add OpenMW to the thread. It’s a open source engine rewrite of Morrowind and requires the base game to run Morrowind but it has the potential to be used to create new games and the devs are looking to expand it to allow the creation of ARPGs as well.
Another worthy mention is Endless Sky, it’s an open source game inspired by the classic space trading and combat game Escape Velocity.
Endless Sky was surprisingly addictive to me, it really scratched the exploration itch. Sadly I played through most content at some point, so now I’m waiting for there to be enough new stuff for me to play again. I really enjoyed it, including the stories and lore and universe!

OpenTTD is good
I love that game. I’ve put so many hours into it
