World of WarCraft is a highly addictive mmorpg with lots of good elements but also has some bad.
That aside let's talk about getting to end game. The quests are many and varied. Your first thoughts after experiencing the game for the first time will probibly be ones of joy and elation. The world is massive and very original. For those Blizzard fans it will feel like a warcraft world. There are two factions, these being horde and alliance. Neither faction can communicate with the other and are constantly at war. Besides that there are multiple races in each faction. Each with it's own culture and unique look.
I would recommend everyone to give WoW a try at least once. Some find it not the MMORPG for them and others find their long lost love. Others burn through the game get to lvl 60 and then go on to other things while others take their time getting to lvl 60 develop a friend base and explore all of Azeroth. Whatever your play style I recommend this game!
