Quakespasm VS yquake2

Quakespasm has a Mac build (https://quakespasm.sourceforge.net)

I highly recommend everyone give it a shot. The remaster has a lot going for it but to truely experience it in this way you should use a sourceport like Quakespasm. The official campaign is nice to get you used to how the game works and plays, but IMHO the real game lies within the community-made material.

There's quite a few options depending on what you want out of your engine! One of the most common and compatible source ports is QuakeSpasm, which uses FitzQuake as a base with a lot of user-friendly options both in UI and cvars.

Jazz² Resurrection is an open-source engine reimplementation of 1998 platfomer classic Jazz Jackrabbit 2. It runs on Linux via Mono. Just like other source ports like QuakeSpasm, Yamagi Quake II, ioquake3 it requires original game data to run that can be purchased in GOG.

So I think for loose .PNG textures, you need to use QuakeSpasm-Spiked. DarkPlaces may work with .PNGs as well. Regular Qspsm does support external textures, but only in .TGA format and only for BSP entities.

u/d10sfan has added vkQuake2, Yamagi Quake II, Q2PRO and FTE QuakeWorld source ports for Quake II Enhanced and its mission packs to Luxtorpeda repo. Thanks to that, native Linux ports of the games can be played as Steam games.

I have been enjoying the h*ck out of Quake II (the Yamagi version, not the Steam version).
