Brie's Quest

Brie's Quest is a 3D adventure game developed by Quarantine Development and published by TDK Mediactive for the GameCube and XBOX.

Plot
Brianna is a spoiled girl who puts her luxuries before anyone else. A week before her birthday, her parents are turned into mice by a woman who was teased by her, and her world mends with that of the woman's. Brianna is forced to go on a journey to retrieve several items for the woman and defeat an unknown enemy in order to bring her parents back to normal. Along the way, Brianna uses this opportunity to try and make friends in the hope of getting more help.

Gameplay
You control Brianna. In order to combat enemies you have to use a variety of gems that give her powers. Per melee attacks, she has a basic punch and kick and a ground attack (though without a specific power-up, the ground pound would stun her for a few seconds.)

As you go on, you can communicate with various kids you find. If you do favors for them, you'll win their trust and they'll aid you on your journey, whether it be helping you get items or fighting enemies. If your ally loses their health, they'll be unavailable until you make it to the next level, but you could bring them back if you give them some of your health.

This also applies to most bosses, where you could potentially avoid a fight if you give them something in return. Some boss groups would have to be maintained, such as giving them money you find along the way to talk them out of bribes from the big bad of the game or providing sacrifices.

Whoever you get on your side would affect the outcome of the end of the game.
