Eve Online. Its an mmo that is older than Wow. And is still going strong.
Okay, you got me.. EVE is indeed a working PvP MMO, that is running on subscription basis... The majority of PvP games however is running either on a pay to win system (world of tanks) or on a cartel market with a different game (LoL and similar).
So claiming "fixed" when changing a quote to say, that this game were running on Cartel market and not on PvP is pretty silly.
