For me it's been: CoH, GW, DDO, WoW, EVE, TR, AoC, and now WAR. I've tended to return to WoW as my home base. But I'm totally sick of the PvE grind and play style. Most games only get a month or two. I love playing WAR. I plan to stick with it for the RvR. But I'm really worried it won't thrive. I'm also dabbling again in Guild Wars, which has astounding quality and beauty.

Future MMO surfing will likely include Jumpgate Evolution and maybe Star Trek Online/Champions (Anybody know if there'll be a good PvP system in these?) and maybe Guild Wars 2. But most of these are solo. My very small, jolly, gay guild is mired WoW. And I'm very careful who I join forces with beyond a simple PUG.
