I like the one that focuses on martial arts sword skills
. State of Divinity is a good example. The main story revolves basically around finding and mastering the "72 Stance Demon" (if that's correct lol) swordplay manual from the Li family. Of course, all great series have everything else in it to balance things out and make it more appealing and three dimensional. I am really partial to the classical wuxia style of film-making:
Missing and highly regarded Kung Fu manual
Young handsome hero that go through severe hardship
Damsel in distress that cant help but fall in love with the young hero
Diabolical villain that no one can beat except the young hero
Falling off a cliff only to survive and become unbeatable after 20 years
The beginning story always starts 20 years ago or 18 or 16.....
Deadly poison and hard to find antidote, but always manages to find
Good and bad sects fighting for world dominance ....
I'm sure there's more to add
