Nintendo's sold over 50 million DS units in the US

Nintendo's twin-screen wonder has seen almost as many reinventions as Lady Gaga, so it may not come as a huge shock to hear that the DS (in all its guises) has now sold over 50 million units in the US. The home entertainment maestros are still chasing similar success for its three-dimensional sibling, the 3DS, however. Nintendo has managed to sell almost half a million three dee units units after its weighty price cut, but there's now some very potent competitors seeking their own slice of the (portable) gaming pie. Good luck, Nintendo, you're probably going to need it.

Super Mario 3DS

Ah, the game that we have been playing since we were young kids is soon going to be available in 3D on the Nintendo 3DS handheld. It is a fun game and making Mario run in 3D is quite nice. There are a lot ot puzzles in the game so you need to save those much-needed Mario lives.

Nintendo 3DS

3DS has twin screens like the earlier DS. However, 3DS has a 3D upper screen that doubles the fun. The 3D is OK, and you don't need to wear any geeky glasses. There are plenty of game choices, including our favourite Mario.
