Guild Wars 2

Could it be possible for players to nominate an IP address that is valid for accessing their account, either through account management, the forums or the game itself? I happen to play on a static IP address, as I am sure there are others that do as well. By allowing me to nominate that IP address alone to have access to my account, the ArenaNet software would then know any attempts to log into the account (or game) from somewhere other than that IP address would be fraudulent.

Rift had a really good system for this. Essentially if you’re playing on your account and Rift doesn’t recognize your computer/ip/whatever it “coin locks” your character where you can still play the game but you can’t sell or buy anything. And in order to unlock it you have to go to your email to get a code.
