It really depends on more than that, as someone who's played a ton of WoW at various times of my life I would say that it's the best case scenario for an MMO that can offer something to everyone, if you have the time it's worth trying. The game itself gets about as deep as you could possibly want and the community can be incredible. it is however best enjoyed when you have at least a few hours to dedicate to it a night to put in the work to be a good community member yourself.

You really get what you give with a game like WoW. The rewards are great, some of the best of any video game experience, but they do not come for free. It really REALLY rewards people who are outgoing and engage in the social aspect.

WoW Forever is probably the best version of WoW for someone looking to start now (I personally like classic better and think retail is trash but ymmv and really good community can be found in all flavors of the game), and there's a lot of hype around it right now.
