I played WoW for a bit but it wasn't my cup of tea. I played on a big roleplay server, and there was almost no roleplay. -WoW- had more roleplay. The big selling point for me that made it better than WoW was it's keep raids, some world pvp, but even those - at least on my server, turned into zergs of empty keeps since no one would defend. It was more beneficial to let the enemy cap and then just recap it when they leave.
Lordy, I miss the sandbox.
