What parts do you want to be similar? Dying Light 2 has a large open world, parkour, and an interesting story and lots of side things to do. Plus its combat is melee plus bow, very similar to Assassin's Creed. Off the top of my head, I can't think of a more similar game, unless you were talking about other points of similarity, like historical settings and what have you. It's in first person, if that makes a difference to you.
The first how ever many Yakuza games had open worlds and melee combat in third person, but no parkour.
Dishonored might be similar. I've never played it. Maybe someone who has can chime in on that one, but from what little I know about it, it seems like it might be close.
