Red Baron off line and Dawn of Aces on line were fun, including the dirigibles and field artillery in the latter.
But the WWI crates would come apart pretty easily from manuevers as well as bullets, and at best most things seemed to be a more feeble and slow motion version of WWII. Which is the way it really was, right?
So, no, I'd rather Aces High stick with refining the ultimate prop and gun vehicles of WWII.
