Mediacl Mysteries:
This game was very creative. It was a complex game composed of 5 individual "minigames." Its purpose was to teach about different diseases, how to diagnose them, and how to treat of avoid them.

Learn the Bones:
This game was very simple and not too creative. It had a good purpose, but it still needed a lot of work.

Stop Disaster:
This game was challenging. It was very detailed and very complex. The creators developed it well.
