Possibly the best multiplayer game I have ever played.
You start of by creating a character who can be a warrior, ranger, mesmer, elementist, monk and Necromancer. After that your thrown staright into a large town where there are tons of other players doing there business. I started of by playing by myself and eveuntlly I needed to be in groups of other players. There are lots of missions to do but you can do whatever you want and explore whereever you want.
The PVP is quite good too, but theres only one type of mode for that type and thats more or less deathmatch. It might have been good to have other types like capture the flag.
The graphics are great even on low spec machines and it has great sound too.
All in all this is a great multiplayer game, one that should not be missed!!
