There are no big dungeons in the game, sadly the maps in the game are all small in repeat far too many times. It makes exploration maeaningless since you will allways see the same maps with random enemies.
It is a complete waste of time since just boarding the ship is quicker and more effective, I really wish you could carry unlimited medicine just like food and water. It's absolutley stupid that I can carry 500 food and 500 beer but only 100 medicine.
What, even your race, class and NAME???
The game suggest that the watcher you play now is different than the watcher that died in Caed Nua, at least it says so in the narration when you meet yor soul in Eothas.
It reminds me of the discussion around Dragon Age Origins where people wanted to have an option to refuse to become a warden. Here you really have the chance to refuse the game.
