There are very few complaints from the Shacknews community about Dark Souls, largely considered by them to be one of the best games in recent years. One of those grievances, however, is the unwieldly Games For Windows Live support. The problem was compounded further when the service was officially discontinued earlier this year. Bandai Namco has finally stepped in to address this by migrating the game to Steamworks.
According to the Bandai Namco Tumblr page, Dark Souls owners will get the option in November to redeem their existing Games for Windows Live tokens in exchange for a Steam copy of the game. Players will have a limited period to transfer over their characters and progress, with a cutoff date yet to be announced. Expect more specific date ranges to be announced in the coming weeks.
