So this is for games & software?  Here's one you might not have seen...

Try out the "Cartridge Challenge" quiz, 75 questions last I checked, at ammoguide.com/

One has to register (free) to play, cause the game saves your score in your profile.  You can stop anytime, login again later and pick right up where you left off.  If you score high enough, you can get listed in the "Top 40" scores.  (I didn't, but it was fun anyway.)
