The strange but rather excellent Dragon’s Dogma: Dark Arisen is now available on GOG, and currently has 60% off the asking price. In the US, that makes it $12.00 USD.
Dragon’s Dogma translated very well to the PC, so there aren’t any major concerns on the porting front. If you were hanging on for a totally DRM-free version, then GOG now has your sorted.
Anybody looking for an open world(ish) RPG that lets you clamber on top of large monsters and hang on for dear life as you try to stab it should look no further. This game will also provide dynamic chatter about the hunting habits of wolves, and regular updates about the masterwork quality of weapons. You can’t go wrong, really.
