An Oracle for All.
Both Ages and Seasons take one of the their goddesses that created the world and brings them forth as starring characters. You go through the games as you would normally, collecting items from the various dungeons and, in the end, defeating the final foe and saving the kingdom of Hyrule.
The nice thing about these games is that they overlap and have extended play once you finish. Nintendo and Flagship have done a good job to provide a password at the end to play an extended version of the game with items carried over. These games are also set up to make you want to play them both.
These are definite games to own if you have a GameBoy.
