I find that I can't play CIV in the modern age or beyond anymore. My jet fighters are being intercepted by fighters and airships. My carriers and submarines are being sunk by ultra-precise, space-based , destroyer launching sattelite weaponry, even if they are in the middle of the ocean, with NO possible way of the enemy seeing them. My transports are being sunk by harbor based naval units which I can't even retaliate against. My wounded units are hunted down with extreme precision and destroyed on a constant basis, and even if I cruise with a stack of 100 ships, the transports/carriers/wounded units get targetted first. Basically my only option is to play a pangea map because CIV 4 naval combat is Teh Suk. It's seriously a game killer, the AI is horribly flawed and I don't see how Firaxis didn't pick this up during testing. Unless ofcourse they assumed it was perfectly ok for the game to play this way.
