ok, more input:
* I'd like to see other food corps than Sid's Sushi. When I found this corp I'd like it to randomely pick one name from the following: Mario's Pizza, Kadr's Kebab, Chang's Noodles, Pedro's Tacos, Joe's Burgers... It wouldn't change anything to the game, just add a bit of diversity. (EDIT: well in hindsight it would certainly change the resources you'd have to collect in order to make your corp's bonuses grow, like cows and wheat for burgers and so on... so it may not be such a good idea, as it would disrupt the balance between corps)
* It would be nice if you could assassinate other civs' Great People. I think they would be tougher to get at when they are settled but still vulnerable. Obviously, that would be a spy mission. Ultimately, it would be good to see an option for conspiracy: e.g you kill one of your own GP (that Martin Luther King is doing a lot of rufus don't you think?
) then blame it on another civ so that your people gets upset at that civ. It's then easier to declare war on them.
* The comeback of the press (as seen in civ1) would help a lot in appreciating the results of a conspiracy. Also it gives a good insight of your own civ and a little more immersion in it.
*Last but not least, the UN should have military power. Each member civ would have to lend a number of units of some type (determined by military power/advance) and these would be controled by the IA, which could decide to intervene militarily in a conflict, for example, or to blockade one civ's trade routes.
Camikaze >>> I know some of my demands are unrealistic, but really, most of it is just wishful thinking, and when it comes to tribute I always ask for the most
