Using my advanced investigative skills (I checked Amazon for new releases) I've stumbled across Dragon's Dogma: Dark Arisen. This comes out in April for the PS3 and Xbox 360. A simpler way of thinking of it is a Game of the Year (GOTY) edition. It includes the original game and (apparently) all DLC.
This helpful video (not mine, I hasten to add) explains in more detail:
It's pretty cheap and people who already bought Dragon's Dogma get some extra goodies (rift crystals and some new armour) as a kind of thank you from Capcom (not sure how they decide you owned the first game. May come after importing a save, which can be done).
If you have not bought Dragon's Dogma yet and like RPGs, especially fantasy ones, this is a must buy. The original game alone is well-worth buying at under £20, and with lots of extras (mostly high end stuff) and increased character customisation this could be the gaming bargain of the year.
For those who do have the original game, it's more difficult to decide. However, I'm given to understand that the DLC has a price tag exceeding the £20 of the game, so on that basis it is value for money.
