Probably only a few bucks. I'm not really sure. If it's in good shape and it still works, maybe $10-15, but that's pushing it. Of course, I'm no expert...but hey, if it works, and you can play it, the LSL games are fuckin' hilarious! Definitely worth playing it
I agree with his price. The only Leisure Suit Larry game that is worth more is the collector's set, which sells for around 30-40 I think. It's a bit surprising, as a lot of the older point and click games tend to be in high demand and used to fetch quite a bit more than they do now (i.e. King's Quest series, etc).
