I regret that I do not have the time right now to offer something in depth. I just wanted to say I am quite pleased with how Entrenchment has turned out and that I look forward to both the next two expansions and the final sum incarnation of Sins, where all the various expansion material may be inter-balanced. That is to say, and this is a secondary aspect of my comment, I imagine that a given faction may find itself better at fortification than at commerce, or another at diplomacy than fortification, etc. .
Anyway, thanks for the expansion. Pretty cool.
