I did post this in a topic but after re-reading the interview I think there's enough in there to warrant a discussion maybe?   Romero gave a nice interview over at the Slayers Club website discussing Mapping, SIGIL, mods ,his favourites and gave a shout out to @Linguica and Doomworld which I thought was cool.   Interview is right here.   https://slayersclub.bethesda.net/en/article/1vt4DnYWjIz6T8KbegBs8G/nods-to-mods-interview-john-romero
