This... is probably the best summary of the Codex I've ever seen.
That said, I do love the place. I firmly believe that the internet is for mad people, and that that's the way it should be. Madness has its negative side, but if I want to talk to anything approaching normally functioning human beings, I'll leave the house. If I want mad, brilliant, maladjusted geniuses willing to wax lyrical about odd obsessions ranging from art direction in RPGs to racial purity to how golden retrievers are genetically modified mutants to how much they want trannies to poop on them, I go to the internet - and for all these things and many more, you can't beat the Codex.
It takes a... special sort of person to survive there with sanity intact. I'm really, really not sure why everyone there is insane or why general discussion is a Nazi enclave, but there you go. For all their downsides, I don't believe there exists anywhere on the internet a collective of people who, as a whole, know quite as much about old-school RPGs as the Codex does. Work your way past the bile and the insane noise:signal ratio and you'll find that their hatred is motivated by the purest love. Love for a genre which has undeniably strayed far, far from its roots, with the original target market being told by the industry as a whole (not Obsidian; they've had their bad moments, but I really like them and think their hearts are in the right place at least) that nobody cares about them and they'll never be catered for again. From the endless well of tears left behind by this act, an act which echoed the way their dad left forever so long ago, the Codex came to be. And all the Codex wants is to look back on the good times, when dad would hold them close and make all the world's troubles go away. But now mum is coming home with another man, who's big and strong and handsome but just can't replace your dad, and every night he beats you and tells you that you're stupid and ungrateful for not calling him father, for not saying he's better than your old dad ever was, and everywhere you go, all the other kids are talking about how cool your new dad is and you know what I mean, right?
