Gw gold players can't play with them or compete against them.
You don't have to spend countless hours on a leveling treadmill to get to the interesting parts of the game, because combat is designed to be strategically interesting and challenging right from the beginning. You don't have to spend hours running around the world to prepare for a quest, because Guild Wars Gold allows you to instantly travel to the beginning of any quest that you've previously unlocked. You'll never spend days playing, only to discover that the choices you made early have left you with a permanently uncompetitive character. The unique skill system in Guild Wars encourages infinite experimentation but doesn't allow early choices to limit a character. And you'll never meet new players only to discover that Gw gold players can't play with them or compete against them because their characters are on a different server than yours; in Guild Wars Gold, all characters live in one seamless world.
