Archived hereTho this topic isn't updated anymore, better formats exist, and there's zilch demand...I miss it man, so I'll give it two cents. Might be more as I clear out old bookmarks.

EDIT: added a couple more old gems. All art there, no tech or game dev yet. I don't think the caliber is high enough for the thread, it's stuff you can search, but they're worth a look. May update, but I don't want to spam this thread.
