Well, for those who are passionate about history, making an historical mod (any mod, not just EB ) is more than just modding a game, but various serious things, like honoring the past, or trying to educate and inform the present. Looking at it that way, it should be understandable why some people get emotional and worked up about these things.

I can't describe myself as passionate about history (maybe an enthusiast), but it takes a certain degree of seriousness to devote hundreds or even thousands of hours to modding a game. It can be taken too far, like anything else. And I've definitely been guilty of that.
