Mod VS Spring RTS game engine

This inspired me to fire it up. Works great! Looks like "we the people" is the fully updated mod. You could go vanilla if you want, but I think anyone still playing is using that mod. https://github.com/We-the-People-civ4col-mod/Mod/releases

Seems the support would be a realistic feature, though, because it's based on https://springrts.com/ that does support MacOS X.

springrts: Designed for 3D rts games. May be worth looking into if that's what you're making. The site is kind of lack luster so I didn't do too much digging around.

...or Total Annihilation Spring, nowadays known as Spring RTS: https://springrts.com/

My current favorite is Beyond All Reason. Before BAR, my favorite was Zero-K. Both BAR and zk use the same game engine, SpringRTS. BAR and zk are very similar to one another, and they're successors for Total Annihilation and Supreme Commander.

Obligatory mention of another open source RTS engine (lineage tracing back to the original Total Annihilation): https://springrts.com/

Non-OSS Engine?

Total Annihilation for sure, the spiritual successor Supreme Commander is great but a bit too different for me. There's an open source recreation that's a bit rough to learn at first, but it's my favorite game of all time called Spring RTS. https://springrts.com/

The other thing is that if you're going to make an engine focused on rts games, you should probably study an existing RTS-focused engine. For example, here's the source code for Spring. Learn what it does, why, and how. You might decide this is good enough for what you want to do. You might decide this is pretty close, and you'll only want to extend it rather than start from scratch. You might decide to still start from scratch, but at least you learned something about requirements/ methods/ etc.

Pretty much any game on the Spring Engine (which Zero-K is on) will work on Linux.
