I’m a big fan of Cataclysm: Dark Days Ahead, a community fork of the original cataclysm which is linked in the original post.
A bit of background: The author of the original cataclysm decided to change focus to a total rewrite titled Cataclysm 2, there’s a tumblr of some feels here: https://whalesdev.tumblr.com/
In effect, the development of the original cataclysm died out, many players and contributors were upset about this. In true open source fashion, a fork begun, named Cataclysm: Dark Days Ahead. It’s a real monument of an achievement. It has been remarkably active since around 2013, with over a thousand contributors.
I can’t think of another open source game that has as many active contributors as this one (can anyone think of some?), it’s truly great if you’re into roguelikes and post-apocalyptic vibes. It a ton of depth, especially the crafting system. A huge chunk of the entities that exist in the world can be crafted with the appropriate skills and materials.
You can go off into the forest, chop down some trees, and build yourself a log cabin and make a little mini Stardew Valley experience if you want, including harvesting feces from wildlife to fertilize your farm. You can make a Mad Max style behemoth of a tank and drive around killing everything in sight. It’s pretty fun once you get the hang of it.
Huge fan of DDA here. Just another detail for those interested:
I usually play the experimental version straight off the build server, but the latest stable is very new and can be found here: https://cataclysmdda.org/
The main changes from the last stable version are 3d buildings (3d in the sense of multiple floors, not 3d graphics) and vast improvements to npcs, factions and base building
+1, the commit hygiene is remarkably good for such an active project, I often play right off master and very rarely run into breaking bugs. When I feel particularly conservative, I switch to the latest tag. ;)
The predecessor of Cataclysm: Dark Days Ahead, right? okay..
Huh, I didn’t know about DDA until now.
The community fork (Cataclysm DDA) was my first open source experience and also the first time I was subject to code review! This brings back memories.
Looks like development on this went from 2010-2013, and no activity since then.
If you want to see more development, the successor fork (Dark Days Ahead) has over 81,000 commits at the time of writing, from more than 1100 people.
