[quote name='ruibing']Is guild wars worth that much? I've been tempted to try out that MMO, but maybe it would be a better idea to just get the first one?[/quote]
I would say so, at that price its almost like buying Nightfall and getting the other 2 free. I bought all 3 and GWEN expansion on or close to their release date. I really enjoyed them, but Destromas is right you really can't solo much, but the Nightfall heros help in that respect and it will eat up a lot of time if you try doing all the side quest, capture the skills, and go after titles. Also, once you beat the story of campaign the first time you'll open up hard mode for that campaing, which is blast if you are looking for good challenge. There is also PVP, but I can't really speak on that as I mainly play just the PVE.
