I wish I knew I tried it at 2.0 launch, Steam launch, & again recently... I just can't get into it. I think if you're after an MMO that's got a good chunk of single-player content that you're in for a treat, but as someone who'd rather walk on hot coals than sit through an MMO story, it just felt like a chore.
Glad to see it's doing well though! I know a lot of people who've played & loved it for years, so there's definitely a lot about it that's good.
