I don't think I own any Stalingrad games, which is why I'm happy Simonitch is designing Stalingrad '42.
I don't own any Stalingrad specific games, but 50% of my wargame collection is Cold War and later, and most of the rest is age of gunpowder stuff.
My WW2 inventory, not counting some stray magazine games, are Spearpoint 1943, a couple of LNLT games, Bulge 20, FAB Sicily, the original SL, Tank on Tank, Rommel at Gazala (LNL), and The Pacific War: Pearl Harbor to the Philippines
WW2 just isn't a big area of interest for me.
I had the ATO Berlin game, but sent it to BC a while ago
