I don't play any WW2 games, and I'm not a 15mm or 20mm player either, but the PSC stuff really impresses me.
Guess I never kicked the "treadhead" obsession from back when I still played 40k.
Hopefully they will continue going strong and expand their range.
I should look into games that can be played with these but at worst I'd like to get a few just to have on the shelf.
