it is one of the best games ever http://www.guildwars.com
It isnt like normal mmorpg like lvl all day if they play longer they are better
but the pvp makes it good player vs player
the player can also fight agounsty other guild with their guild, you need some tactict or you will loss the game :p
8vs8 TS or ventrillo are handy for that

And the normal gamplay is also nice you mission pets heroes weapeon like that max lvl 20 :p so it wil to the skills over a 1000 :p yuo only can use 8 of them in the figt and that makes it fun the right build ect.
