Luca Carminati has the habit of updating arcade classics to get them out of the arcade context (where a game had to be very hard for more profit) to adapt them for home usage, and he does it brilliantly.
After Pac-Man, the author tweaks Dig Dug, adding randomization after the first level, and a lot of little details making the game more fair and more pleasant to play. Once again, this is the best version of the game to my knowledge.
