The party goal is a system very similar to Kotor 2.

At any given time there will be a party of 1 to 4 characters which MAY include the player's main character.

At various places and stages in the game, you will be allowed to switch out members of your party.

We are currently planning to have a 'solo mode', ala Kotor as well.

When not 'actively' controlled, the party members will have 'AI settings', similar to BG2 and/or Kotor 2 that they will fall back to (such as 'Healer', 'Offensive Caster', etc).
