Resistance is £12.99! I love this game and it is still one of my favourite. Other games are:
Virtua Tennis 3
Motorstorm (cheaper brand new)
They're all for £12.99. There are others for £14.99 and £17.99 like Assassin's Creed. Don't know if the prices are the same instore, but may aswell get online.
