One of the things I've always enjoyed in turn based strategy games like Civs, Moo and Alpha Centauri is alliances. Or "blocks". There usually comes a point in those games where you have a couple of allies, another strong civilization has gathered some and then all hell breaks loss and it becomes one team versus another. One block against another. That's really really fun, trying to get stronger civs to join your block before they join the opposing one and such. So I was thinking, why not introduce a mutual defence treaty into GalCivII that would be easier to get then Alliance? That way, you'd have a diplomatic option for people who like to form blocks without interffering with a diplomatic victory option and difficulty.
