Actually its easier to run a historic or modern game than a fantasy one, because the players, more or less, already know how the world looks and behaves in historic games while in fantasy games you as DM have to explain it.
Really?
I don't think this is true, and I'll show you why.
Take two people, on same physical build and abilities and train them both for 10 years using similar training schemes in two different martial arts. Lets say Kick Boxing and JuJitsu. Who wins?
What's the chances of someone accurately hitting someone in a live fire zone at 20 yards using a pistol. What effects this accuracy?
Or, even a simple one, who wins out of someone using a English Shortstaff (which, oddly, is about 8' long) and someone with a Sword?
I can tell you that the more you know about the above topics, the less likely you are to agree on the results.
Dave Arneson, listed above, stated that he used Fantasy precisely because it was easier to run. Easier because it's arbitrary.
Here's what I think, it's easier to run a game when no-one really knows too much about the world it's set in because no-one has contradictory beliefs about what "would really happen".
In historical games, this is difficult because people know varying amounts about things.
In fantasy games, this is easy because everyone knows the same amount. Not much.
