Guild Wars 2

I think this game is very beautiful but seeing the identical looking npcs over and over again is a bit annoying.

Well, depends on what you’re pointing at.
Main towns like Divinity’s Reach, The Grove etc.. has same NPCs, of course. :P
But if you are visiting small outposts in all over the Tyria, they’re many unique and different ones aswell!
The Pact has also quite many appearances of NPCs.
