The first three are surprisingly good, especially the 2nd and 3rd, and especially if you like those old style Sierra. Oddly charming, and Larry really is just looking for love (and often finding it), he's just a bit of a hapless loser.
Regardless my point is it is a good series and surprisingly tame. Sierra adventures have a ... style but I love them. The main thing is: save a lot. More than you think.
