GameSeek are the cheapest around the both the PS3 and Vita versions of Dragon's Crown. In some ways, the Vita version is the best as you can use the touchscreen to pick up items and unlock doors, leaving you free to enjoy the excellent fantasy scrolling beat 'em up action. If you prefer local to online multiplayer, then get the PS3 version instead. Both are awesome really. The RPG elements are fantastically deep and the game's been patched recently to unlock an extra difficulty tier, which has ensured it's effectively nailed the card flap shut on our Vita's again.
