Unvanquished VS julius

Unvanquished - FPS arena game with some RTS elements. C++, libRocket

I would recommend Unvanquished instead. It's basically the same game but FOSS, much more polished, and there's a small but active community. Servers are often empty, but people will eventually come if you join one and you can play against bots in the meantime.

I enjoyed Tremulous as well. There's currently a sort of revamp (ignoring GPP/Trem 1.2), called Unvanquished. https://unvanquished.net/

Unvanquished the fork of Tremulous (who's not developed anymore) could fit.

Unvanquished

You're probably thinking of Tremulous, which is also forked as Unvanquished. Started life as a Quake 3 mod if I remember correctly.

Julius) - Caesar 3 clone. C, SDL2

Cesar 3 was also rewritten (https://github.com/bvschaik/julius), and besides the marvelous work from the author that has allowed fans of the original to experience it on modern platforms and further preserve it, it has also invigorated the community and spawned other efforts to further enhance the game.

It’s a shame that many companies do not agree with such an approach for dormant or abandonware properties.

Picked it up on GoG a while back and had a great time with it. Keep thinking about it every so often despite not finding the time to play through it again. Last year I decided to teach myself a specific game engine by replicating the game. I am not a game developer so I was in over my head and I stopped but I revisited the project earlier this month and managed to get basic map rendering working with the original tiles. The julius project together with citybuilding-tools and ZeusMapper were a great help to learn how to read the original asset files. I see all the Caesar 3 maps on this subreddit and would love to at least be able to generate those for Zeus + Poseidon one day even if I never get any actual game logic working. However just trying to figure out the logic for how cliff and rock formations are rendered is enough to make me think that will never happen. What I wouldn't give for a peek at the original source code.

Caesar III was recently reverse engineered, and is now receiving updates (project Julius on github) and new features (project Augustus on github).

There is Julius if you want to play it today https://github.com/bvschaik/julius

I just got my Steam Deck and one of the first things I'd like to try is to play the old city-building Caesar III. I searched a bit and it seems that the only way to run it is through https://github.com/bvschaik/julius/releases/tag/v1.7.0 installation. Can you please explain how to do it?

An old city builder called Caesar 3 has a Steam release, and an open source implementation named Julius that works natively on linux.

there is an open source copy of this game called Julius that fixes some aspect ratio issues of this game and is free to download (you need to have bought a legal copy of the game for it to work though). they also made a version called Augustus that adds a bunch of new things, like the monument system from later games ins the series. https://github.com/bvschaik/julius
