You control your own character who will improve and become more powerful the more you play. The game is multiplayer which means you will meet many other people in the world who you communicate and trade with. Guild Wars http://guildwars.mmosite.com/ Gameplay for GW is different than most MMOGs. It's far faster, and there's a lot more to do. There are TONS of skills but you have to put them together in combos which means that you can use the stuff people have proven to work, or make up your own and try to make them better.
