I got Warhammer 2 Total War recently and I've been really enjoying playing it.
When the first one came out, there was a general opinion that it's a great Warhammer game and a great Total War game and in the case of the 2nd game I can only agree.

After decade of playing Warhammer Fantasy Role Play which was set up in the Old World and specifically in the Empire, this one caught my attention because it takes place on all the exotic lands that are south and west of it and have all the exotic races (Warhammer Fantasy battles fans might have known better about them but I never got into it).

All of the playable sides in the game are first divided into races, which then are divided into factions. Races differ a lot. They have access to completely different units and buildings but also campaing mechanics. Think of a difference between Medieval total war factions from west europe and middle east, but more. Plus completely different looks gives you a different feel. This translates well into replayability. Previous Total War game I played was Shogun 2 where basically everyone had access to same samurai units (with few exceptions) so I felt the difference a lot after switching to Warhammer (don't get me wrong, Shogun 2 is a cool game and I liked it a lot). Factions of the same race don't differ much, with the exception of getting a different starting location, Legendary Lord (all armies in the game are commanded by a lord, and every faction gets one unique Legendary Lord), and as I saw it DLC lords get a different campaing mechanic sometimes.

The four main races (which are High Elves, Lizardmen, Dark Elves and Skaven) get the same campaing objective, which is to perform a certain ritual and win the final battle, at the same time preventing the other factions from achieveing the same. To do so you need to gain the ritual currency (named differently for every faction but essentialy the same thing) by completeing various quests and controlling strategic cities that generate it per turn. Total conquest is not necessary to win the game but still avaiable. DLC races have different objectives and don't really have to take part in that ritual conflict to win the game. So as Tomb Kings faction I have to travel around the world and get into possesion of all the books of some ancient necromancer before the other Tomb Kings faction do that first, and as a Vampire pirates I have to trabel around the world and plunder and murder and dig up treasures until I become most infamous walking corpse on the sea.
