Cool curiosities! The chocolate quake source port is great as well. I've always wondered why there wasn't a chocolate doom equivalent for quake. It was nice to see its announcement earlier this year, so I've been quietly following its development ever since. The guy behind it did a great job, now we just need a crispy doom equivalent for quake!
I also wonder where is that tortoise texture from. Seems such a small thing to have the effort to create art for during development.
I am not familiar with chocolate doom what makes it better than any other doom source port?
There are many good source ports of quake, I always liked darkplaces but it intentionally and willfully tries to push improvements so not really for purists. There is stuff like fitzquake/quakespasm that stays much closer to vanilla quake and if you like quakeworld ftequake.
