It's somewhat ridiculous how many older video games are still comparatively expensive.  Supply and demand seems to dictate that if you want a used copy of Metroid for the Nintendo Entertainment System after all these years, you'll still pay upwards of $10.  Want Super Mario RPG for the Super NES?  Somewhere around $45 please.  Final Fantasy VII for the Sony PlayStation?  Why, you'd need a bank loan for that!  Then there are the games for consoles few people loved, such as the Sega 32X.  Retrogaming with Racketboy has put together a list of the cheapest, best games for the failed platform, and much to my surprise there are actually enough quality 32X games to warrant such a list.  The obvious games like Knuckles Chaotix and Virtua Racing Deluxe are included, but then there's a few of which I'm unfamiliar, such as Tempo and Kolibri.  Tempo definitely sounds interesting, and best of all, it's affordable!
