So much in this civ design relates to new/overhauled game mechanics.
Mechanics we can hardly evaluate for now.
- How exactly does the world congress and the favor-system work? The increased favor gain might be strong.
- How did they rework the cultural victory and tourism in general? I've never built a national park (hence I don't even know about its requirements), but the bonuses might be better than they would turn out in the current game.
- The new ressource system is also just known "in theory", but nobody really experienced how it "feels" in a real game. Canada migth be quite powerfull with little land (and thus less strategic ressource spots). This will also apply to the late game and ressources neccesary for civilian use. This makes the Canadian peacefull game-style more feasable.
I am not sure about the farmes on tundra tiles. Is a farm improvement enough (even wit hthe "feudal trianle" mentioned above) to make this tile type useful enough? I think, an additional bonus might have been neccesary.
Anyway, I always wanted an "ice civ". Here we go ...
