Dragon Age: Origins (70% Off)
Price: $8.99 (70% Off)
If there's one thing I can say about Dragon Age: Origins apart from the fact it's a mechanically solid classic RPG, it's that the morality system in it is unlike anything else BioWare has ever produced. Rather than simply monotoring your ethics on a sliding good/evil scale, each decision you make in the game has a direct impact on the relationships between your character and your party members. Managing the politics of your choices is remarkably difficult though; you can't please everyone all the time!
Do note that the Complete Edition which is on sale comes with all of the game's DLC, including the Awakening expansion and the nine different content packs.
