World of Warcraft was a truly great game. I remember playing in the open beta days as an undead mage and all the way up to BC. In vanilla I played until 7AM in WSG even when I had tests in college.
Sometimes the interaction with other players in the battlegrounds got pretty toxic so I quit after returning briefly in Pandaria and completely deleted my account, but if you don't mind the occasional people berating you or your other teammates for something you didn't do wrong I think it's worth the money. I don't know if Roleplaying is still a thing, but when I played in Shadow Council it was really fun to interact with all the people and their versions of their characters' background stories. I might even play again if there was a way to waste my time in places like the old BRD and BFD, trying out new things with friends, but none of my friends are playing now...
