4. I love to exterminate the Aztecs when they are an opponent.
5. I refuse to play the Aztecs.
Ha! I'm the same way with the Iroquois. They just get so big so fast and become so dominate in the game that I've come to fear them. Once they go Commie, the Iroquois are an unstoppable killing machine. If I find them on my continent early on in the game, I kill them off. If I find them in midgame, I start arranging alliances to clobber them (more than a couple of times they've wiped out all my allies--they're the Gray Ooze of Civ3).
If I find myself up against them in the late game, I just quit. I know I'm gonna lose, so why drag out the pain?
Naming ships is a little useful, but numbering those galleons and transports is
essential. Otherwise you lose track of which one is transporting which unit if you've amassed a big armada in order to assault someone else's continent.
Finally, when I play America, I don't use the suggested city names. I'll either name a city based on the closest geographical equivalent in the RL America, or I name the cities after smaller American towns that aren't on the city name list (Galveston, Newport, Miami Beach, Encino, etc)
One thing I miss about Civ 2 was that you could use your spy to rename an enemy city. It's petty, but I'd always rename them "Idiotville" or "I suck" or "Please destroy me, Bucky."
