I have one request for you.
Can you put also at name EU/NA?
Would be pretty cool in my case which I'm lazy to type everygame and look if they have EU servers.
Adding the link would be too much so just EU / NA in ( ) would be nice.
MapleStory has an arena styled PvP
Added Dungeons and Dragons Online to the first category thanks to these poor guys: Why PvP in DDO sucks? - DUNGEONS & DRAGONS ONLINE®: Eberron Unlimited™ Forums

Open world pvp (Can even kill people in your faction)
Perma death (Once you run out of clones)
Faction vs Faction (8 factions total one of them being mercenaries which you can actualy hire through the contract system)
Ability to take over colonies/planets, in other words meaningfull pvp.
First person and 3rd person combat (No abilties, high level armor and weapons or any of that crap you get a gun and wether you live or die is dependent on how good of a fighter you are).
Invenvtory Drops on Death (with the exception of weapons and implants)
Most Wanted System (players receive penalty points for doing illegal actions, the 20 or so players with the most penalty points are listed as most wanted and when you kill one you will receive a reward for doing so)
The game also allows for the police faction to arrest and send people to prision (raidable).
This is new feature to Dragonica on gPotato.eu.Dueling System
A highly requested new PvP feature is now available; you may now ask any player to have a PvP duel almost anywhere in the world, no more messing with different modes, rooms or other details when you just want a quick match with your friends or enemies.
Maybe they already update it in Dragon saga i don't know.
Lineage 2 recently went free to play and has open world PK with penalty and Castle Sieges.
Darkeden has open world PvP against other races or your own race and blood bible wars.
