So ultimately then, the game will be used with my 20mm plastic collection, though best to try out the rules with the little blocks first.
Only sticking points were (1) there's a little more complexity, though you quickly get used to it and (2) the rules for squares, where cards are withdrawn from the hand, so as to reduce flexibility - seem fine, but were a little clunky on the day.
So, we tried the first scenario from the main game (Rolica, 1708). As usual, and in line with what we've already seen, some great and tense moments, and all finished quite quickly. A unique system for modelling fog of war, and some of the strategy cards come just at the right moment (or wrong moment, depending on your point of view).
I can see the 'epic' version of this working well with non-wargamers (although suspect there might be beer involved too...)
