Thats rubbish Jonesy. If there is someone to your North that someone to your South wants to make war with, then you CAN sign an Open Border agreement with the Southern nation in Civ4. Then they can just tramp through your nation to attack your northern neighbours without you getting involved. I should know because I have done it several times myself. What civ 4 prevents, however, is the rules-raping situation of signing an RoP, moving a huge stack right up to someone's cities, then declaring war on them & catching that city in pretty much the same turn. Now THAT is cheesy. It is also, might I add, completely off the topic of this thread.
If you want to discuss the expansion, then please do so, if you simply want to b***h about how much better you liked Civ3, then may I suggest you start a seperate thread?
