The last Zune HD firmware update apparently had one more trick up its sleeve: 3D gaming, finally. And while the new games might be late in coming to the Zune Marketplace, they look worthwhile. And more importantly, they're free.
Anyone with Zune HD 4.3 should be able to mosey on over to the Zune Marketplace, where they'll find a few new surprises. Or what would have been surprises, if I wasn't about to totally ruin them right here:
• PGR: Ferrari Edition
• Lucky Lane Bowling
• Vans Sk8
• Piano (it's a piano toy, not strictly a game)
• Audio Surf: Tilt
It's not quite the same as having an open marketplace with a full SDK—presumably Microsoft's actively helping push these things along to keep Zune HD users interested—but it's a start. [HelloFromEurope—Thanks, Korneel!]
