Gametrailers put up a couple more new interviews with the team behind this. One of the interviews talks about the relationship between Jason and the various Greek gods that are important in the story. Hermes, Apollo, Athena, and Ares are the most important in the story acting as a way to level up Jason. Which god you dedicate certain action to will effect you abilities and powers. They also act as a dialouge tree with different choices per god.
The other new video talks about love and how it effects the story. Jason's soon to be bride gets killed before saying I do, but after Jason has given his vows, so he goes after the golden fleece to try and bring her back to life.
Overall I think the game is shaping up nicely. Iwish they would give us a release date already though. read
