Rob Blanc was officially my first game, but I thought it was utter crap, so it wasn't for months later when I stumbled upon Larry Vales. It gave me that gooey warm feeling...like when I stick my hand in the microwave. So through that, I found AGS and quickly fell in love. It inspired me to make Ace Quest...which I did.
Larry Vales, along with snail quests, moose wars, and my own games, is one of the only adventure games that I have on a back-up cd. I still think that Phil Reed hasn't been equaled in the community, as far as comedy.

Edit: Note, ROb Blanc was my first official AGS game...the first every adventure game goes to mixed up mother goose.
