Just thought I'd mention this in case any one is interested.
There's currently a City of Villains promotion running, existing players are given one 14-day CoV trial code to give to someone.
(And if that someone buys CoV after the trial, they and the existing player they got the code off get... sandals! And laurels. They're to go with the toga. It makes sense really.)
Anyone who's currently playing should have a 14-day trial code, so if anyone else is interested in trying CoV, poke me or shout in here.
