I still have the physical EncycloAlmanacTionaryOgraphy that was required to start The Island of Dr. Brain. Though I was probably just a bit too young to fully enjoy the game, I fondly remember clicking on everything I could and seeing what would happen. Every puzzle provokes distinct memories, but it's the antonym/homonym/homophone puzzle with ants that I (embarrassingly) remember most vividly having trouble with. This game is a true edu-tainment classic!
