Hi, I think we will be going down the hexon route, but I have given the decision to my wargaming chum. I'm getting the evidence together for him, and I'm up for hexon, although I have to change a lot of the rules to fit. We worked in a huge area marked out in 20cm x 20cm squares, but converting our rules should be easy enough, simply time consuming. I worked out that we are looking at a table area in excess of 1500 hexons for a single layer. I'm hoping that Kallistra can oblige with some appropriately priced bespoke items, such as a sunken road/stream hexon, to give some depth, but of they cant I may have to actually do some modelling of my own... for the first time for ages. I confess the possibilities of hex gaming do excite me.
I'll stick my hand made battlefield table graphic up, so you can see the task ahead, bearing in mind that, given we are operating in 20mm, hills will need to be more pronounced, involving a lot more height stacking, or the finding of some substitutes [such a polystyrene foam cake blanks
