Want fun and excitement? Play Guild Wars...what more do you want?
I still have things to do on Guild Wars and the other Guild Wars games, as well as the expansion(Eye of the North). I even have a blog on here about advantages and disadvantages, which helps to give you an idea of what Guild Wars is like. But, overall, I believe that the game is brilliant because of the gameplay - tons of missions, quests, landscapes and characters.
The guild system is very good too, which is suggested at a lower level, since guilds do help usually for beginner and experienced players. In addition, you can own your own place with your guild and alliance. Furthermore, the missions are challenging are sometimes hard if your a beginner, as well as having a lack of help at the time. Since some missions need people or heroes to get you pass the missions; such as Sunijang District Mission, where you need two people(including yourself) to carry the two items: the spear and the box. Though, some people will say that you may not need them, it is advise to bring them anyway to help you with the mission.
Overall, there are a few disadvantages; in being a bit too hard for beginners and only able to reach level 20, however this is being improved for Guild Wars 2 and Guild Wars' advantages do outway the disadvantages. Have try at it and you will see what I mean, or if your not sure, then look at reviews and game places for a more trusted viewpoint if so.
