There is no monthly fee for Guild Wars. Its alot different from other MMORPGs because there are only lots of peopel in the many towns. Once you go into the countryside, its only you and your party of up to 8. There is a badass team fighting arena with things like cap the flag, king of the hill, etc... The PvP is awesome because you can instantly create a max level character (albiet with no good armor or weapons, so u have to play the roleplaying game). Expansions are coming out.
