Todo: Elements relevant to Valve's engines (ex: skybox format, colored lighting, translucency, BSP format, etc.).

Important:Transparency and Translucency:

Only translucency is supported in vanilla; alpha testing requires certain source ports (Notably not in Yamagi).
Translucency is only supported on worldspawn textures and SP2 sprites, and cannot be used on brush entities or MD2 models in vanilla, due to the usage of the BSP tree for alpha sorting.
Compare to GoldSrc, which supports translucency on any brush entity except worldspawn (as well as models and sprites).
Some source ports (such as KMQuake2) support translucency on brush entities, but exhibit the same alpha sorting issues as GoldSrc.

Yamagi Quake II - Actively-updated vanilla-friendly source port. Singleplayer-focused; multiplayer may be too insecure for netplay.
Q2Pro - Multiplayer-focused source port, with added security fixes, optional anticheat, and many enhanced graphical features
KMQuake2 - Feature-focused source port
Q2RTX - Fork of Q2Pro with real-time raytracing
