I actually thought it was older than 30. I remember playing Sam & Max: Hit The Road in high school. And I could have sworn I had this as well, but never finished it. Then in early college I picked up a LucasArts collection that included Full Throttle, The Dig II, Day of the Tentacle, and Hit the Road. But even then that would only have put it about 29 years old and already in a collection after about a year.
