I think one of the issues in this discussion is the difference in perspective between Americans (who do generally believe in what the rest of the world calls Rampant Capitalism) and the rest of us (I was born and live in America, but spent 25 years in Europe in between).
The American perspective is that the creator owns it and has the right to sell it to whomever they wish on whatever terms they wish.
The alternative perspective is that there are reasonable standards that apply to everything (the whole 'common-law' concept).
Thus, to an American, Firaxis has the right to demand that I lug my external CD drive around if I want to play cIV on my laptop that does not have an internal drive.
To the others, Firaxis has the right to be paid for the game, but once I have paid for it, I can do pretty much whatever I want with it apart from making copies to distribute.
Similarly, to the Americans, Firaxis has the right to charge the same amount to everyone, even though that might mean that people in countries with lower standards of living cannot afford to buy it.
To the rest of us, this may be legally right, but since copies of cIV are potentially limitless, they would be dumb to do so.
I don't think that this dispute can be resolved, because it does boil down to an almost religious faith on both sides.
I would like to thank the Moderators for allowing this debate to continue and to thank ALL of the contributors for keeping our tempers under control and keeping this discussion rational.
