To be fair, I don't know too many people who ever played a LSL game did so for the plot anyway.
I never played any of them.
When I was a kid, I couldn't get my hands on them, and when I got old enough to acquire the games I assumed they would be less satisfying than...er...other things I had discovered around the same time.
How bad did leisure suit larry get?
I'm quite enjoying monkey island. Realistically, there are enough of these adventure games (good ones at that) laying around that you should probably not run out of junk to play for years.
