Up until now I've played most (but not all) of my AH games with Azathoth as the AO. Why? Because I'm still learning the game. Azathoth has a generous doom track and does not add a lot of additional complexity.
But now I feel like I want to branch out a little more and broaden my AO experience. But I don't want to set myself up for failure by picking AO's that look easy, but in reality aren't. For example I recently tried a game with Hastur. I figured the long doom track would help and the 8 clue tokens needed to seal gates would not be too big a deal. Was I wrong or what?
So what I'm basically asking for is a rating of AO's from easiest to hardest. (I'm not talking about final battle difficulty after the AO awakens.) Which AO's would be a good next step after Azathoth?
*NOTE: I only have the AO's from AH, IH, and KH.
