I would very much recommend it to people who are a combination of:
-Enjoy slow-build strategy games
-Enjoy roleplays where your stats go up very incrementally
-Enjoy the ROTK story

So for me it was an easy sell. This game improves on pretty much all elements from the original ROTK8, and adds a few new bits like the Tales to help give the scenario you're playing some vitality. It's a fun mix of the usual strategising against your foes but you have strong control over the narrative so can really make things go off the rails.
There's a lot of content if this is what you like, but really do watch some gameplay videos to see if it's what you like - those who are expecting something more in-depth strategically or in a roleplay sense will be very disappointed. It's its own flavour.

Also, do not pursue Lu Bu.
