One of the most anticipated titles at ATARI's booth was Neverwinter Nights 2, the second installment of the RPG that takes place in Dungeons & Dragons' Forgotten Realms universe. The sequel will introduce 10 new companions that players will be able to encounter and join as they travel across the land of Faerun. With the new characters, players will also be able to add an additional three people to their party and thus increase each battle's complexity in not only the different fighting combinations but also personalities, dialog and back story.
These new characters will also react differently based on the choices you make. The more your character's choices coincide with your companion's choices, the more that companion will reveal to you (as far as background and information is concerned).
This new element to the game should help to add a lot more believability to the characters and could very well go a long way in making you think about the consequences of your actions before you make a decision.
