Before we venture on, there is an important change in the game to pay attention to. From a 2 player co-op the game is now turned into a 4-player co-op game. However, unlike other games you can not only play cooperatively, but also competitively. You can, for example, prevent your fellow players from reaching their goals and even kill each other if you would like to do that, although that might not be very efficient. The story is made such that you need to cooperate in order to advance, but there will be plenty of room left to compete. Each playable character in the game will have a different origins story and because of that also different motivations and aspirations that might even be conflicting with each other. However they need each other, as they are all sorcerers on the run and Larian has made it such that you will not be able to do everything on your own.
Swen mentioned an example, which is not in the game, to clarify this. Suppose we need to go to the north to meet a general. One character wants to kill the general, the other wants the general to recognize him as his son, the third needs his help to defeat a legion of orcs and the fourth wants something else from him. We all need to go to the north, so we help each other to get there, but we do so for different reasons and sometimes conflicting reasons. You can't all get what you want in the end, so you need to compromise, or they just fight over it.
