I'm currently researching this but do you know how long the game is gonna be? I'm hoping for 15-25 hours in length, so I have more chance to play it. I'm still not sure if I like this genre though I like Oblivion.

Oblivion is a first person rpg set in a medieval fantasy world, game length between 15 and 400 hours

Bioshock is a first person shooter with rpg elements set in a Cult of Rapture setting, length might be 10-30 hours?
