NES Remix 2? Not out 'til tomorrow. Child of Light? Next week, on April 29. At least you can play Mario Golf: World Tour today - in a demo.
As for what's launching today, there's the last of April's Game Boy Advance games in Yoshi's Island: Super Mario Advance 3, and a few other bits and bobs too - as ever, we've got the full list of new releases after the break. Finally, there's also a new two-week sale on Joindots' games, including Secret Agent Files: Miami and 3D MahJongg.
