We love Dragon Age: Origins here at Dealspwn.com. Sure, the world feels like somewhat derivative fantasy fare for a while, but superb characters and combat make it one of the best RPGs of the last generation. What's more, its Awakening expansion added another 15-20 hours of exceptional adventuring. If you're just getting round to it (we've all got backlogs!), GAME are selling a physical copy of the ultimate edition for less than a fiver, saving you a few quid.
However, if you only want the base game, protempest @ HUKD points out that GamersGate are selling an Origin code for £2.54.
