Game and Engine Development General
The Game and Engine Development General, or /gedg/ is for the discussion of creating games and engines, including the many tools and libraries involved in dev. One large incentive for posting on /gedg/ is code blocks. On /g/, you can share code like so
[code] paste your code here [/code]
We have an IRC channel #/g/gedg on rizon!
Also make sure to check out the /gedg/ compendium: https://rentry.org/gedg!
