There is one huge bad thing about it depending on your point of view: the game tells you nothing. Like, nothing at all. Got a quest? Solve it yourself, no waypoints no question marks no nothing and you'll have to find the hints yourself from asking people.
Seriously, I found a love letter to a woman from the guy she was cheating on her (murdered) husband with which said their love would be so much easier if only her husband was dead. I take the letter to her and after a short conversation the quest log updates with "she denies that this proves anything".
And that was it, no further clue.
Edit: You also get bonuses for actually role playing, including arguments within your group. You can choose between threatening, charming or reasoning with people to get an answer and you get bonuses or lose points depending on how you act. It's kinda fun if you're roleplaying the 2 characters in your party differently because they'll start arguing with each other.
And then I lost a few hours worth of progress because I accidentally used quick load instead of quick save... Edited, Aug 20th 2014 10:29pm by Aethien
