I guess Sept 2nd is as close to an anniversary we have for Monkey Island. I made the gold master on the 2nd but it probably didn't appear in stores until Oct. There was no "release date" back them. It annoys we when people say Monkey Island "released" today.

@grumpygamer i was about 12 when i saw MI2 running on a demo PC, playable, at the electronics store. guybrush stood at the swamp, near the voodoo lady's hideout. i was instantly fascinated. only later did i learn there was a MI1, which was my sequel i guess, and i was besides myself with joy. the acidic grog mug riddle was incredibly annoying. but unforgettable. y'all did good.
