I'm new here, and to CiV 4 as well.
I got it of the Steam summer sale a few days ago for 10 bucks. Anyways, I went ahead and installed Beyond the Sword, and figured out most of the basic gameplay elements from reading Sisiutil's guide.
I'm trying to develop a proper strategy and stuff, but I always get distracted by my units. I seem to have an itch to wage war, no matter the reason or the logicality of war at that time.
Yeah, I was like that too. I would always be plotting a war, and you can get away with doing it when you're starting off if you're at a low difficulty setting. But sooner or later you'll find out it generally doesn't work cause you'll do things like wreck your economy/tech (potentially), make everyone pissed at you (and you can't take everyone at once), etc.
Found the bloodlust sort of went away as I learned more about other aspects of the game, like how to set up cities properly and use tile improvements better. Still tend to not give in to AI demands and declare war too much.....but not as bad as before.
