I had 4 years in FFXI and I absolutely loved all but the 2-3 hours lfp... lol. I also played close to 4 years of WoW and I enjoyed that aspect of MMO as well. A couple years in EQ2 and Lotro, and they all filled some void in my endless appetite for MMO's. All mentioned are great games in their own right and although similar in some ways, are still very different experiences.
