It doesn't take long to get into World of Warcraft; it doesn't take long to get out of it either (opinion based review).
For the sake of cutting this a bit short I will get straight to the point: World of Warcraft is a great game, great fun, great people and it lasts as long as you want it to last but it's combat in general just isn't as appealing and isn't as challenging as it could be; [In fact, I played the game for about two months and managed to reach level fourty-six in half that time] - too bad.
All in all, from it's great atmosphere to it's great "fun factor", World of Warcraft offers, and don't let some review by some stranger stop you from buying the game and trying it out yourself - I mean, there are still people playing that game long after I quit, so it all comes down to opinion, and this was mine.
