Got that spiffy new Zune HD but feel like your squandering your Tegra powered goodness?  Well fret no more as the latest firmware update 4.3 (released last Friday) opened up the world of 3D gaming to Microsoft’s plucky little PMP.

Along with fixing that odd little playcount issue, the 4.3 player update added support for upcoming 3D games and apps which have now arrived on the Marketplace.  Though the list is still rather small the good part is that all the games are (as promised) free!

On a personal note I seriously hope this means that support for full-on community development, and a paid marketplace to encourage said community, is on the way.  The day of Xbox Live Arcade merging with the Zune Marketplace is coming, I can feel it.

Here’s the game list:

• PGR: ferrari edition, a 3d racegame
• Lucky lane bowling, a 3d bowling game
• Vans Sk8: Pool service, a 3d Skate game
• Piano, a simple piano where you can play your own tunes on
• Audio Surf: Tilt, ride your music – you choose a song that the game will turn into a roller coaster track for you to ride
• Checkers, I don’t think you’ll need a description for this one

Update: Engadget fired up PGR on their Zune HD, uploaded a video and had this to say about it.

That Tegra chip is no joke — the graphics in PGR: Ferrari Edition are easily on par with the PSP and quite possibly better, with intricate textures, high-quality reflections, and smooth framerates. The other games aren’t nearly as intense, but they’re just as smooth.
