The progression of the story will be non-linear, as all of you are sure to like. And as a non-linear story would suggest, multiple endings await based on how they've interacted with the world as well as what alignment the party is. The world itself is very reactive, as we saw in Arcanum, meaning that how you act will affect how NPCs will act to you. Some of this depends on abilities and attributes and some depends on options you choose for dialogue. Of course, some dialogue options won't be available to characters without certain attributes. For example, a nasty ogre guarding a dungeon will kick the crap out of you unless you're wearing a cloak of a certain type, but even then, you'll have to have a character with diplomacy skills in order to weasel your way past him without a really nasty fight. As you would have expected, there are a lot of different ways to get past each situation depending on the makeup of your party.​
