Dig Dug looks and sounds great, until you actually try to play it. Then "great" becomes "half decent." The graphics are as detailed as the arcade game's, and the background theme is nicely reproduced by the Commodore's sound hardware, at least when it's not falling out of sync with itself. Those occasional sound problems, together with lots of unnecessary differences and a lack of most of the original's music, turn what could have been the best port of all 8-bit systems into something a whole lot less. It's still Dig Dug, and it's not a bad Dig Dug, but the Commodore can do much better.
