EQ 2 is not what it was in the beginning, and that is a good thing.
You CAN solo now, no problem.
You can also group if that is your thing.
You've got a lot of options and EQ2 is much better than it was upon release.
As a hardcore gamer who has played almost every North American MMO in existence, I can tell you that this game is WELL WORTH a revisit.
It's better than Lord of the Rings, WOW, Guild Wars, Vanguard (blech), or any others.
Right now, in its current revamped state, Everquest 2 is the best fantasy MMO available.
As a consumer, it is also affordable. If you do a digital download you can get the entire game, plus all expansions, for 39 dollars. It includes a free 30 days. I thought this was well worth it.
