During a period when most educational games were about rote learning, the third Dr. Brain game taught thinking skills instead, like spatial reasoning, organization, and task management. While a big chunk of the minigames don't land well (the Synaptic Cleft ranching game is a bust), the game respects the player's time and intelligence and lets you tweak the games' complexity without any penalties. Big points for trying something big and for making it so lively and animated.

Did anybody actually like the Synaptic Cleft?

One of those games I played as a kid that would probably be very underwhelming to go back to but I have a lot of nostalgia for. Funny rat wears silly costumes.
