I have been having great fun playing these two games. I would like to find similar games where you have to find and combine pieces to continue. There are also some interesting mini games that need to be solve in order to advance.

My two favorites of this type of game, apart from the Magic Encyclopedias, are Flux Family Secrets and The Treasures of Mystery Island. If you like the Magic Encyclopedias, you won't be disappointed with either of these.

Enlightenus is also similar, IMO.
