Beginning of the adventure is challenging because Talos will constantly destroy some buildings and go back to his spawning place for a little while and then repeat that process. Takes some planning to get Jason to come to my city and kill him. Hera comes a little later and makes it even more challenging. Overall, fun and easy adventure to play.
Cons in my opinion: Maybe set up some more openings by the water for triremes, docks, and trading? I managed to make it work so maybe it isn't a big deal.
Atalanta is impossible, I believe, to summon. I completed all the requirements to summon her, but one requirement is blank. Therefore, it's impossible to complete it.
