Digger

The Good
Digger is just incredible for a 1983 game. It did almost everything right -- graphics were state of the art, music was pseudo multi-channel, and gameplay was so addictive. I still play it from time to time, and actually enjoy it.

The Bad
It has only 8 levels. And also if you die in the middle of a higher level, it's sometimes really hard to finish that level without dieing again.

The Bottom Line
I'm not sure whether the new generation will like Digger, but it's still fun to play.
