I just finished my first game of Civ5 (yeah just got it today since I live in Europe) and one major problem I had was the incompetence of the AI (at least on archipelago map type). I was playing on prince difficulty and when I got frigates and later battleships the AI posed no challenge for world conquest because they failed horribly at one aspect... The AI didn't build decent navy so I could just go park my frigates/destroyers/battleships of the coast of enemy city, bombard it to 1 hp and capture the city with a single infantry unit with amphibious promotion while the ships also hammered all enemy units that got near the city.

I'm gonna try another game tomorrow with another map type to see if the navies are only thing the AI suck at.

Despite the AI Civ5 is awesome and I hope raising the difficulty makes it a bit more intelligent.

Unless they make the e-reader coffee and juice proof I rather have paper newspaper. I can't even count how many times i have spilled something over a newspaper while reading it at breakfast table.
