Found Dragon Quest IX in the reduced games section of my local Asda. They have dropped it down to £10.
Been looking for this cheaply for a while.
Players travel the world, conquer fearsome monsters and unravel an epic storyline. During their journey, players will encounter mighty opponents in fast-paced battles, and also interact with a colorful cast of characters. Players can even leave the game active in their backpacks, pockets or purses and still interact with other players via an interactive "Tag Mode." Information about players' characters can be wirelessly transmitted to others, and treasure maps and customized greetings can be exchanged automatically by players who come within range of one another when their games are set to Tag Mode. Players looking to enjoy a variety of different game activities can take on special side quests. Some downloadable quests will continue the main storyline of the game, while others offer standalone missions.
