Arguably the "first" RTS. Not sure about SDL2 support. But clean C/C++ might be a good candidate for WASM port to web. Still need .pak assets...

Recall many abandonware variants of Dune games floating around the web back in the day. With some incredible cut scene art ;)

SDL2 worked well through Emscripten, so I'm pretty certain it'll work well under WASM?

Yes, SDL2 works equally well in Emscripten in both asm.js and wasm.
