While I started previous to Tom's work...Moldvay was the frst time I actually UNDERSTOOD alot of what was going on in the game (rules-wise). Therafter much of my games became B/X hybrids with AD&D stuff added. The Moldvay set IMO is bar none, the best introduction to D&D ever..clear and conscise, but plenty of room to work in/around with the rules. Incredible game. I still have my copies.
I always loved all of Tom's work..whether it was the re-write of B3...The Lost City, Stockade...whatever...it was good, and X2 is def one of my all time faves. Tom's adventures were just that...adventures...even with simple story lines, they always had a great mix of the elements that make up a great night of playing the D&D game.
Even when Tom and a bunch of others got canned, and he went off to Pacesetter, I followed him, purchasing TimeMaster, Chill, etc..and then Lords of Creation...which was quite similar in look to that Moldvay basic rulebook.
He left a big impact on me gaming-wise, certainly as much as Gary.
Thanks Mr. Moldvay. May that gold tinted sword the cleric gave you always be sharp, and at the ready!
