In the Seventies and Eighties, Korg synthesizers were a byword for musical cool, albeit one that cost the average electronica nut thousands of pounds. Fast forward 30 years, and 25 quid buys you a cartridge packed with a sequencer, synths and drums which you can use to craft the symphony of your dreams. Although it's available on the DS, this is less of a game and more of a tool. But for anyone who ever longed to create tunes on a Korg it will be music to their ears.
