It seems to have been difficult to get through the month without hearing or seeing something about Dragon Age: Origins as there has been a widespread advertising campaign on-line and on TV.
I don’t have a powerhouse PC yet it runs mostly smoothly on my rig with reasonable loading times (some of the bigger battles with lots of effects do cause a bit of stuttering at times, but not unplayably so). It’s a new game system (with a pen and paper version planned) but the play style, particularly the combat system will be familiar to players of KotOR, with a real-time, pausable, system. As with KotOR and Mass Effect, much of the game play revolves around the multiple companions, who will converse between each other and with you about various things, some exchanges are quite humourous 🙂
Depending upon which version you bought, when, and where, there are various DownLoadable Content (DLC) packs, some for free, some paid for, with more in the pipeline. There is also a flash game, Dragon Age: Journeys which can net you some extra DLC items for achieving various goals within it.
