Thanks Jon - agree totally on the terrain, in the smaller scale I can get the representation of a hamlet with 2 - 3 buildings instead of one and perhaps have two hamlets and an extra wood or two on the table.
As for army size, in Epic, I use two bases with 40 figures giving a unit frontage of 120mm, in 20mm I use the same 2 x 60mm bases with 20 figures to give the same 120mm frontage and in 28mm, I use 2 x 80mm bases also with 20 figures to give a 160mm frontage - so the difference for me between small scale and big scale is only 40mm extra on the unit width.
What is different is head count, but for me, I prefer 20 bigger figures than 40 smaller ones.
There is also a difference in depth, so my small stuff is 20mm deep and the bigger stuff 40mm deep, so brigades in depth take up less space and probably look ‘more right’, though the impact on the table because we are talking depth is not as much as one assumes.
So for me, it is the terrain that is the more obvious area of difference and for my figures, I never want to be painting up 20 battalions per side anyway. 8 - 12 units is fine and for big battles, I am a boardgamer, so I tend to rely on those to deliver the bigger game.
taking all those circumstances together, my own likes, dislikes and needs and wants will be different than a lot of other gamers, but I suppose we are lucky in this niche hobby that we can sit back and choose from that array of product.
I also have 28mm Wars of the Roses and still on their sprues, I have 1066 armies, both of which I think are just aesthetically better in the larger scale, though that ignore practicality of course. There is plenty in the mix for me to toss around :-)
