Guild Wars 2 let's you swap worlds/servers that you play on - once a week, if you wish, but for a fee.
All characters linked to your account will migrate to your new home, and all subsequently created characters will live there (unless you swap again) as well.
I'd pick Andy Roddick - he's a good server.
Thankfully, it sounds like Europeans can inhabit US servers and vice versa. Changing a region means being "logged out for a short period of time while your account is moved", developer ArenaNet explained.
The fee for swapping worlds/servers is 1800 gems - the micro-transaction currency.
Guild Wars 2 will also let you "guest" on other worlds/servers free of charge, although doing so has some restrictions. You can't take part in world versus world battles, for instance.
That's because world versus world battles pit entire worlds/servers against each other in huge, hundreds-strong battles. And you fight in world versus world battles for the prestige of your world/server - not some "guesting" holiday home.
World/server transfers are up and running for this weekend's Guild Wars 2 beta test. You're given 2000 gems free of charge - enough for one transfer should you need it. The world/server guesting feature, however, won't be available in this weekend's beta.
The meaty list of servers available during this weekend's Guild Wars 2 beta are below.
Eurogamer recently flew out to ArenaNet's home in Seattle, US, to find out more about the people making Guild Wars 2.
