Oh yes, it is very easy to leave it at that. But it is even easier not to log in on this forums, click this particular forum and even read what is written in this thread.
"We all know". What exactly do you mean? Dirtworm is not a new user, actually he's one year older (join date, not age) than me, and he has Civ4. So most likely he knows. But I've seen tens... no wait! Hundreds of threads in which people are confused because of something like this, especially when it is about the editor. Want some links? You moved yourself some of those threads in the Creation and Customization forum. I did the respect-worthy work of clearing things from your posts.
I, for one, did not know Civ4 doesn't have an editor until I actually wanted to edit the rules in the worldbuilder. And I got it months after it went out, in all this time I've been lurking and posting a lot in the Civ4 forum (mainly complaining about various aspects which I didn't like). "We all know" says it all. Maybe you are right, it's not hard to leave it like that. I'm wasting my time trying to help in this forum, and all I get is someone telling me to leave it at that, and that I'm annoying. You are right, I'm wasting my time on this forum.
