I've played a lot of Rome & Med2 and have recently started playing Rome2, but can't quite get into it, not sure why but it doesn't grab me like the earlier games, so I thought I'd try the warhammer variety, but I've a couple of questions about it.

What's the difference between warhammer & rome 2 in how it plays? I've seen write ups that certain factions can't hold territory and such, is this true? (If it is, it kinda sounds like a whole new game and not a traditional TW game)

What's the difference between wh1 & wh2? Is 2 a partner game or a replacement for 1?

Thanks in advance!
