What do you think about the game World of Worldcraft?

Hello! I never personally played this game but I know about 10 of my friends who do play WOW. Even if my friends didn't play this, I have seen this game everywhere. Stores, magazines, websites, etc. I think this is a good game from watching my friends play and based on what people said about this game. This game consist of a lot of elements and there's a variety of games within the game itself. There's different kind of characters you can be and different tasks to be completed. There are solo tasks and also group tasks where you can play with your friends or live people together. There's crafting, fishing, selling, etc. But I do noticed that a lot of people are really into this where they can play for hours nonstop without getting up or eating. Or they would have multiple computers where each screen is a different character. Sometimes I wonder how can anyone be so into a game but then I realize it's a hobby and it's similar to someone who can cook, hike, sew, read, write, or any other hobby for hours. Some are healthier than others or more reasonable than others but it all kind of comes down to an individual preference.
