I have only played a little bit of one of the games (Don’t remember which), and wanted to get back into it, but I am wondering which game out of all of them has the most factions that are unique from the others. Meaning I don’t want to see two to three factions having the same units but under different names. I mean unique units to that faction. Perhaps all the factions have unique units. I don’t know. Remember I only played a little of one of the games and so I don’t know much about it. Thanks.
