So I picked up Civ V and all the DLC during the steam sale and I've been pouring all my free time into it since, but I was wondering, what's everyones favourite way to win? So far I've won by United Nations which I found a little easy to manipulate by buying up all the city states at the last turn. I've also won by Utopia and by Science (all from the same save reloaded) and I have to say science victory seems to be my favourite so far.

Also has anyone beaten Diety yet? I stupidly tried it out and got owned, any tips for winning?
