I just wanted to inform you of my players' decision.
After I introduced the APs, they started a long debate on which one they should have run.
I stayed neutral, I stepped in only to correct any wrong statement about particular APs.
After 2 hours and so of discussion, the contenders were Curse of the Crimison Throne and Wrath of the Righteous so I decided to have them vote.
Wrath of the R. won with 3 votes against 2 so I'll be runnig that AP and I'm happy with this resolution.
I was quite surprised by the fact that they completely overlooked Kingmaker and Skull'n'Shackles, but i guess they just don't like free roaming.
Thank you all again.
