Pretty much all of
BF stuff is nice, but the cost to have enough to make a decent board you are looking at £400 - £500.
Their Vinyl roads are very nice, but you need at least two sets, then you need lots of buildings hills and other elements.
I think things missing......Would be Rail, I use HO but it's not a good scale,
TT is closer but extremely rare and therefore expensive. Rail was key to WWII, much of the Armour was transported long distance by trains.
Depots, key Rail junctions and ports were vital to allied supply lines, which post D-day where very thin and the ever advancing Armies stretched this Supply chain to breaking point, Antwerp was a bit of a mess as the port was smashed when it was captured.
I think PORT and RAIL facilities are lacking, you make them youself.
I really like some of this but it's expensive as hell.
Especially as you need to model, prime, paint flock and match it to the Board.

I will be grabbing one in the next 12months and building a Bespoke Game board that I have in my minds eye.
