I STRONGLY suggest that if you're interested in pvp you check out
http://rakion.softnyx.net - this game is the only real one I know of its type thats online.... look it up on you tube type rakion to see its gameplay. There is a cashshop but in the end the game is heavily dependent on skill, you aim your own attacks, you are in control basically and its a room based game but you do have chars/levels/stats/ just take a peek at it.
www.gunzonline.com - is a matrix style 3rd person fps its also a really fun game check that one out too.
The best part about both these games? Pvp from the first 5 minutes to the last 5 minutes. These games are not PvE oriented they were built for pvp.
Quite honestly I don't think there really are many good MMORPGS they are all designed to absorb a lot of time, are monotnous, slapped together in certain areas, randomly wandering bears? kill 10 bears for a quest.... oh yeah really well thought out -.-..... Until things change in the mmorpg scene they are a waste of time imo. Good luck! Also check out a single player game called Mount & Blade.
