So far Arenanet has said that they're not affected (even if GW1 is listed), since their relationship with Playspan was selling GW1 trough their online store and no account information was ever shared with them.
CCP said they were a timecode reseller and also no account information was shared.
Runescape also asked its name to be removed from the list of affected games since they didn't share account information either.
That said, it's probably a very good idea to change at least your password for any TSW account, specially if you use the same password than in any other MMO.
