I recommend playing it yourself. Some reviews are honest and credible. others, like by Stephen Ten Eyck are false and are made by those who just do not like the company these days. WoW is one of the most important games in history. Paving the way to other MMO's. While the graphics are up to par with the standards of the modern era, it regularly receives expansions, patches, updates, and has a robust support system by the developers and the community.
