I wonder, whose quote is this: "Can I try playing too? Even though I don't know how."
I didn't copy it from anyone, I swear - I came up with it myself! :D
As for knowing how to play, just the other day I learned about two or three features in Heroes 4 that I didn't know about. So, I don't know everything/can't do everything, I need to learn, learn, and learn - as Lu41k said.
And that's what I'm doing on every map, honestly - and I enjoy it. :)
