*** where have the ipod classic games gone?

App developers have probably stopped developing for iPod Classics now and turned to newer devices due to there being more users on the newer devices. Read Frequently Asked Questions (FAQ) for iPod Click Wheel Games - Apple Support as it may help you a bit.

Where have you been these last few years? All iPod clickwheel games were removed from the iTunes Store as of October 2011. Any you still have in your library can be used with a compatible device, but they can no longer be purchased or redownloaded from the store so keep a good backup.
