Hinnom was among the first to be eliminated in Kingmaker, also in the game I subbed - beer, Hinnom was on the verge of extinction in the first year. I will admit that Hinnom can be very powerful IF played correctly, as Baalz pointed out in his very thoughtful guide.
Omnirizon: I do understand what sandbagging means, and there is dictionary.com even if I did not.

Hinnom's position in this game really came from our great peaceful relations with all our neighbors.
Dragar: Being Hinnom already shows its downside. My offer for 15N hammer was never answered. This should tell you something. Besides, you would rather attack peaceful and honorable Hinnom rather than Mictlan?
Jazzepi: IMHO choke points are OK, it just favors a more defensive style instead of being rushed everywhere. However, the map is not close to be balanced. We will see this more clearly when VPs are taken.
