thanks for the replies everyone, I'm currently having Great Fun with Earth18, and the ideas for adding new Civ's to restrict the space for REX are interesting. I guess that I should try out Earth 32 also. I'm currently on the way to a victory with Cyrus on Monarch level (having lost on Emperor), I'm undisputed No1, and it would now be almost impossible to lose, but still only have about 20% of the land area. I've no chance for a cultural victory (not having planned for it), but I'm terrified of the amount of time I'll have to put into the game, to get a domination victory on this map. I've heard that para's and bombers are the way to a quick domination. It's now 1860 , and I've just researched flight, rather than slog thru Europe with my SOD's, would people recommend that I wait until I have more speedy troops ?
