As far as what players need to do, the process of moving from the old Game Center to the My.Games launcher is a simple matter of firing up the former in order for it to update itself to the latter, then log back in and agree to the ToS. Those who did not use mail.ru, bk.ru, list.ru, or social networks for registration are offered an additional linking service.
For those who perhaps forgot, the My.Games launcher is essentially the international version of the My.Games’ previous Games.Mail.ru platform. It’s the place where a variety of MMOs live, including Conqueror’s Blade, Revelation Online, and as of last year, Skyforge. Since the My.Games platform is an international one, it might also be one more step in the ARPG’s ongoing march to a release here in the west.
