What was the best year for MMOs?

Some time ago I became frustrated that I couldn't find a comprehensive timeline of when MMO launches and expansions happened, so I decided to make one myself. I've always been fascinated with the overall unfolding of history across this genre, and I've also wondered one important question that comes from such examination: What was the best year for MMOs?

There are definitely some years that have seen more releases than others, but maybe the answer to that question doesn't lie in sheer numbers. Perhaps it's in quality or significance. Was the best year 1997, when Ultima Online came out and really put MMOs on the map? Or was it perhaps 2004 with its incredible trio of City of Heroes, World of Warcraft, and EverQuest II? Would you say that 2009 was significant, as DDO ushered in a wave of sub-to-F2P conversions? I think there's even a good case to be made for 2012, what with its large amount of high-quality releases.

But this isn't about what I think; The Daily Grind is about your opinion. If you had to pick the absolute best year for MMOs, what year would that be?

Eh... I think during the MxO years...
