Does Guild Wars operate on a single shard like Eve Online?
The entire game is divided into servers, some stationed in the US, some in Europe (Many of which have local language restrictions to facilitate community). This structure allows for the MMORTS-style combat known as WvW, wherein three different servers are pitted against each other to control a map and defeat the others every two weeks.
Each zone has multiple districts, referred to as "overflow servers", to reduce lag and optimize performance. You can, however, jump to any local "shard" at any time as long as there is a member of your party there.
There is also (coming soon) a Guesting system wherein you can play on any server any time.
Server selection does not restrict communication, PvP options (with some exceptions involving WvW, and server guesting/switching), or Guild membership.
