First, a short introduction to the game itself. Guild Wars is an online action role-playing game or as the makers put it; 'a Competitive Online Role-Playing Game'. You could call it 'massive' because players all log in on the same server and can see each other in the cities which act as gathering places. It's even better in that than most mmorpg's; people from litterally all over the world get connected to the same network and can play with each other without the infamous server-soap you are used to. But once in the quest-areas you are adventuring in a place for you (and/or your party) alone (these zones are also called instances). That means no interruptions from other players or otherwise said no camping/griefing issues that most of the massive multiplayer online rpg's are experiencing. It also means that you'll never get the thrill of player vs player (PvP) or a real 'seamless world'-feeling in these quest-areas. Still, the PvP-aspect gets enough attention in special arena's, tournaments and such where everyone will meet his maker sooner or later. It's also here where the 'Guild'-part of the game's title really comes into play. Something that people will love to hear is that players won't be charged a monthly fee. You just buy the game in the shop or online and you're all set. On the other hand; a lot of new content will eventually be bundled in optional expansions. We'll have to wait and see how frequently ArenaNet will release these expansions and how much these will cost.
