For me its simple: the Germans had more varied and more interesting tanks, armored vehicles, planes and uniforms than our soldiers had. Andy has produced various versions of exactly four American Tanks: various M4 Shermans, an M3 Lee, an M5 Stuart and an M24 Chaffee. About the only American tank that saw service in WWII that is left to produce is an M26 Pershing. Add to that a couple of Tank Destroyers (one of which, the Hellcat, was already done) and a Priest self-propelled gun (already done) and that's about all there is to do. The Germans, in the other hand, produced Panzer I, II, III, IV, Panther, Tiger, King Tiger, Flak Panzers, Marders, Nashorns, Wespes, StuG III, Stug IV, Jagpanzer IV, Jagpanthers, Jagtigers, Sturmtigers, etc. Not to mention the miriad varieties of armored cars and half tracks. Andy could spend the rest of his career producing German vehicles and never run out of new stuff to do. And have you ever taken a look at the experimental planes the Germans were working on, not to mention the variety of planes that actually saw service? Andy did one of the German experimental planes, a Blom & Voss 141b (which I have in my collection), a recon plane with the cockpit out in the middle of the right wing so that the pilot and observer can have a true 360 degree field of vision. Andy also did an ME262 Swallow, the first operational jet fighter. There are just tons of really cool German aircraft as well.
