2. i play regnum and its rvr open pvp and i enjoy it a lot. we had a really long hard 1 hour fort war just now.
then again i have heard GW2 is good so maybe thatshould be checked out too.
Be warned - I am a major player of Regnum Online the mmo. I've been playing it for about 2 years and rarely go without logging in at least once a day. You can also look at good alternatives to Regnum such ase Aion online and Aika Online.
