This was one of the big ones I was reading about at Gen Con last week.
Ernest Gary Gygax Jr.'s Marmoreal Tomb Campaign Starter
Though it doesn't really need my support at this point, it is full of Original Old School street cred and even newer OSR Old School cred.
Frankly I like the idea that it will have addons to work with D&D 5 and White Star.
Personally I am looking forward to the Modern Horror and Castles & Crusades conversions too.
In any case this looks like a lot of fun.
