Darkfall was the best, aim-based pvp with tons of skill involved
Played like a FPS but with more drawn-out fights
Personally I prefered Unholy Wars over the original Darkfall because of the camera angles and archery arcs but the servers were closed down because Adventurine as a company is literal cancer
There are 2 classic Darkfall versions out right now but I didn't really get into it. If you're willing to go through a learning curve and to fight with a clumsy UI I'd give it a try.
