It would seem I am the only person with the sense of devotion, or the free time, to update Mojo.
Gametap recently added two titles from each of Humongous Entertainment's old graphic adventure game series for children, Pajama Sam, Freddi Fish and Putt-Putt, to their library. As you already know, Humongous Entertainment was the successful (and now defunct) kids game company that Ron Gilbert founded some years back. Their point 'n click adventures used a form of the SCUMM engine (hence their compatibility with SCUMMVM), and some of the earlier Pajama Sam titles were worked on by none other than Dave Grossman. The general consensus on the series seems to be that the earlier ones were great, and the later ones (not published by Humongous) less so.
But you all knew that. I however haven't played more than a bit of one of the games long ago, and so can't comment on their quality or the chronological position of the installments that Gametap is offering, but if you have Gametap you should obviously play them. I think these are the earlier ones from each license. Someone with actual facts or sufficient knowledge of these titles should correct me in the comments. Anywho, here's the list:
Pajama Sam's Sockworks
Pajama Sam Games To Play On Any Day
Freddi Fish and Luther's Water Worries
Freddi Fish And The Case Of The Missing Kelp Seeds
Putt-Putt Travels Through Time
Putt-Putt Joins the Circus
Update: More Humongous titles have been added to Gametap's library.
