You can always try out DDO, great game. Theres also S4 League and SUN online. Come play with me if you want =D
Reputation: 34I would suggest DDO for you guys. From your list, do NOT even bother with SUN or Rohan. They're boring and tedious.
If by RO you mean Ragnarok Online, that's also a great choice. It's a very very good game, albeit a bit old.
Reputation: 10To the guy who said pservers are harder to learn. I started out on one lol, so once I get to iRO it was so easy to understand(grindan was just harder)
