iortcw VS Spring RTS game engine

https://github.com/iortcw/iortcw - iortcw (Civvie 11 used this in his review)

Return to Castle Wolfenstein can run mostly fine on modern hardware, but if it doesn't, there are two noteworthy source ports that can run the game: ioRTCW and RealRTCW. The former is simply gives the game more stability and tons of fixes while keeping the classic RTCW feel, whereas RealRTCW is a full overhaul of the base game, with higher-quality textures, new weapons, rebalanced gunplay, and other changes: https://github.com/iortcw/iortcw https://www.moddb.com/mods/realrtcw-realism-mod

Is this the right link? https://github.com/iortcw/iortcw/releases

Link: GitHub - iortcw/iortcw: Merge of ioquake3 features and fixes into RTCW code bases

And remember to check out the two open source projects called ET: Legacy and iortcw.

In the end, it feels to me that providing opposition to hostile business models is the only way forwards, even if piracy is notoriously bad in the industry and there is ample competition, so not doing DRM and even having parts of your project be open source is probably financial suicide, as evidenced by the occasional thread on /r/gamedev about someone having their game be essentially stolen and it being uploaded elsewhere and someone else getting profits from their hard work.

Linked, because it's actually pretty interesting:

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.
