Are we paying more for less?

OK answer me this, what features and abilities does Dom3 add that M2TW doesn't? I'm trying to compare the two and decide which I should invest my money into because other than the "magic" aspect I really can't see what Dom3 brings to the table that is different or better... From what I understand the diplomatic functioning is much more limited due to being primarily a go to war with everyone game, the politics aspect is largely non-existant due to the nature of the game (as opposed to having to deal with the Church, the various other nobles, Crusades, Jihads, Briberies, assassinations, etc.), and the combat is largely more of simply choose the right groups and outnumber the enemies hoping for good enough "rolls" rather than being able to use actual tactics like flanking, luring, ambushes, etc.

Basically what makes Dom3 "better" in terms of features and gameplay?
