I'm not totally certain, but I think the game just looks for the CD when you start up, but you don't need it to play after that. If that's how it works, could you not attach the CD drive to boot up, then unhook it to continue play? I've never used a laptop, so I don't really know.
I agree it might be terribly inconvenient to need the CD if you share your machine with other users and they put other CD's (music?) in the drive. My computer is all MINE. Heaven help anyone so foolish as to try to touch it.
I thought that might be it,still kinda inconvenient, but I solved the problem by now, by uhh...

...magic. So I am up to v1.22. By the way, I just realized this, but if you sign an alliance, you have to stay at war for 20 turns. That explains why my rep gets trashed sometimes. And why nations go to war with me with no warning.
By the way, I got those two cities (and one more) in a peace deal, so the oil is all mine.
More questions:
1. I hear some talk about exiling a civ (to an island usually) what is the purpose of that? Is it bad for your rep to have destroyed the last city of a civ?
2. I have read conflicting info on culture flipping probabilities. I captured the Inca capitol (Pyramids and Sun Tzu) by marching two armies (3cavalry and 2guerrilla+infantry) and simply taking it. Now I am afraid to lose it, but I almost have flight, and I'm thinking of airlifting more units there (and to a few other cities I'm worried about. I heard that with a big enough garrison you can ensure no culture flip, but I also heard the opposite... So?
3. Strategic question: On the other side of the world, Netherlands had about 1/3 of the second continent group, there are four civs on the group, should I get them allied against the dutch or should I pick them off in ascending order of power. Dutch have a tech lead over everyone but me, so I was thinking they might be able to take cities to their South, while I took their Northern cities, and make them refrain from attacking by placing lots of defense there.
4. How do your spies become veterans?
5. I am researching Flight now, 7 turns (just starting), should I wait for it before I go Communist?
6. Is Communism really that bad for Commerce, Is it good for it if you have a lot of spread out cities?
