I'm confused about wether to want Spam or Carthage.
Dude, can't we just have Persia?
Think about it: Great UU, Great Trait Combo.
(Sometimes in my games I just skip Knights altogether and keep pumping out Immortals, because, they're cheaper to build and have same attack-I really don't mind about mobility when I have Immortals conquering my enemies, )
Really though, if Arnelos (he's great about debating, I see,) could post a summary of Carthage that gives all the plus/minus and some Spain supporter could do so for Spain, maybe in a thread in the forum, then it would be easier.
Actually, I'd probably better go to the team forum and look because it's probably there.
EDIT: Fixed some flawed logic (i.e. asking Arnelos to do a summary of both civs and then asking someone else to do one of Spam again, )
