Not only is the He111 vital for many early scenarios, INCLUDING Battle of Britain, it was a daylight bomber before and after its night bombing prominence. Various different models served long after the Ju88 showed up (Ju88 taking precedence because it was easier to build, FYI). Later models of He111 had multiple heavier gun placements, including a 20mm cannon, MG131s, and were used to air launch buzz bombs later in the war.
It was just as versatile as the Ju88, just a little more outdated because the airframe/powerplant development took a backseat to a cheaper plane.
Just keep in mind spitfires and hurricanes can barely even catch our post-BOB Ju-888A-4 bomber, and we have NO suitable bombers to use in THE most popular scenario run through the many years of Aces High scenarios. I think it's been run more than any other scenario bar none.
