I made a mod with a single file (.pk3) that on it's own is an IWAD and contains every game/mod shown in the list you see. All loadable on their own. Proper music, skyboxes, and all.
Can't share it, due to it containing the commercial games, but I WILL make a version with a ton of MEGAWADs rather than MEGAWADs + the original games soon-ish.
