I think after playing WoW myself and seen gameplay trailers from Guildwars, that WoW is far better then Guildwars. The only plus I see for Guildwars is that you don't have to pay any fees for it except buying the game ofcourse.And probably there are a few factors that decides which game your are gonna play.- If you are willing to pay to play, WoW will be an option- If not it's definitly Guildwars- If you liked to play the oldschool retro "Warcraft" games you also will go on with WoWAnyway what is your opinion?Greets,Greli
