Stormfront Studios' Forgotten Realms: Demon Stone has been added to the Good Old Games catalogue, giving you a chance to experience the action-heavy RPG-lite (and more of R.A. Salvatore's writing) without any sort of DRM getting in your way. And at $9.99, it's pretty cheap, too.
Keep in mind that we have a dedicated subsite for the game, should you need any assistance making your way through Faerûn.
