Yeah, Arlo, but MOST the CT fights are at least same period matchups, right? I was thinking about the fun Central American matchup with late WWII fighters. It was historic although it occurred after WWII, if I recall correctly.
How about ...
Actual or Likely Mostly Historical Matchup Fights Arena

Scenario Theater
Scenarios have always been the essence of Combat Theater: specific limited engagments re-creating limited time engagements between historically matched-up equipment or occasionally offering what-if limited time engagements between historically matched-up equipment.
And ... and ... the Main Arena and all AH areas have combat, but ONLY the Scenario Theater has ... scenarios!
scenario: "an outline for any proposed or planned series of events, real or imagined." (Webster's New World Dictionary)
