If you've never played a minute of it, you should try it. I was never a gamer, and frankly don't consider myself to be one now, after 7 years on and off of playing the game. It runs on Macs, and it runs on most computers, you don't need a gaming rig to play it, so it worked for me.
Word of caution- it can be a huge time suck, because you can log on and 6 hours later, you have no idea where the time went. There's a guilt factor, for me, and I know others, who prolly should have been doing something more productive with their time. But I admit it, I love the world they created. And I'll probably aways get the latest expansion just to see what they've done new.
The game has changed, but like life, you can never go home again, as they day. That magic of our first weeks playing can never be replicated.
Very easy to learn and play, and things are spelled out more clearly now than they were 7 years ago, in terms of how to meet your in game objectives.
