This is pretty but there are some pretty big methodological problems and other errors https://squid-protocol.github.io/gitgalaxy/museum-of-code/doom-dna/

One that stuck out at me: reporting that chocolate-doom is 5x the size of linuxdoom. Ignoring that the chocolate doom source tree is the source of four separate games (doom, heretic, hexen, strife), network and TUI support libraries

Also doom3-bfg is in there!? That’s not a classic doom game at all

Couldn’t resist reporting these https://github.com/squid-protocol/gitgalaxy/issues/7811 https://github.com/squid-protocol/gitgalaxy/issues/7813
