It's 1979 and TSR has FINALLY released the Dungeon Master's Guide for this new version of Dungeons and Dragons called "Advanced"!
Plus, they've even started publishing modules instead of relying on third party companies like Wee Warriors or Judge's Guild.
Okay, let's see what's available!
D1 Descent into the Depths of the Earth
D2 Shrine of the Kuo Toa
D3 Vault of the Drow
G1 Steading of the Hill Giant Chief
G2 Glacial Rift of the Frost Giant Jarl
G3 Hall of the Fire Giant King

T1 The Village of Hommlet
You might even grab one of the new 'basic' modules that are out now
