I notice there's a thief action space. I know this will make me sound like an anti-confrontation whining Euro fan... but what's that about? It seems incongruous with the rest of the game. Can Phillip or any playtesters convince me that it's a worthwhile addition to the game without wasting the leader's whole turn by denying one key resource?
I wouldn't call it overly nasty or confrontational, because it's one option among many, and the impact isn't what makes or breaks a turn.
It's less powerful late in the game when resources are more readily available to all the players. But early on, it can be a real magnet for the player first in turn order - why place a pawn on a map space generating a single resource, if you can place a pawn to get you a resource of your choice and hurt your opponent at the same time?
One of the things I really like about this game is how the value of certain actions and possibilities will change as the game progresses. This forces players to constantly re-evaluate which choices should have priority for them.
