After studing the sample scenario on their website my first impressions of the game:
there will be a lot of game boards which could be combinated together! (according this scenario 8, maybe more!)
I couldn't see any additional/special terrain hexes on the board, but don't forget, that's only a pdf file of a sample scenario!!
The units are defined through each separeted unit card numbers, not through colours!
In the first sample scenario there are blue, green, red, white and black colours; but different units could have the same colour; like french cavalry and infantry have the red one.
The length of the game is determined through turns and the winner is the best terminator!
Each scenario has his own special rules, like depleted groups and special formations for some units and there will also optional rules.
The producers tried to make a unique game with some original ideas.
