*AHEM, Curtiss fanboy hat on.*
The Curtiss Hawk 75 (P-36 for USAAC) did more than fight for three weeks in France. It was used by more airforces than any aircraft I can think of, on both sides of the conflict.
From France to Finland, to North Africa, to America's first air battle of the war on Dec. 7th, to China and South East Asia, to air forces in South America, the Hawk 75 was there. Sometimes successful, sometimes not, but it was a ubiquitous type and deserves a proper place in any WW2 flight sim.
And besides, it just looks so good.
