Is it possible to add the Kingdoms expansion to steam, if you own the phisical CD? I was able to add the main Game with the CD-Key, but the Kingdoms extension doesn't have a CD-Key. Can anyone help me?

Can anyone genuinely help me??. I'm a HUGE FAN OF M2TW but I feel I need to ask whether to buy this expansion pack.

Is this an unmissable expansion for a fan of M2TW??. I'm really excited about playing as Ireland/Aztecs/taking part in the Crusades against Saladdin himself.
