I haven't played it myself, but I haven't heard much good about it from my friends who have tried it out.
I'm currently playing EverQuest 2 as my MMO. I did long stints of EQ & WoW in the past, with short stints in FFXI, LoTRO, and Champions Online. I fired up EQ2 at the end of December and the game has come a long way from when I last did the trial.
I'm playing it with a few old friends from EQ1.
I'm currently in WoW. Did EQ, EQ2, DAoC, and then went to WoW because most of my friends moved there and I was impressed by the quests and lack of zoning. The days of fighting with my back to the zone entrance are becoming a distant memory in my mind. But I will say, I played EQ2 waaay back when it first came out. So much may have changed.
Now awaiting Starcraft 2...... it's been a long time coming. My friends and I still play SC 1.
