Gamer 2.0: About 27 years ago, arcade games like Dig Dug and Mr. Do! offered some good arcade fun with a simple concept about digging underground to defeat monsters or find cherries. A year later, a PC game called Digger appeared with a similar concept, but with the goal of collecting gems in what was very much a clone of Mr. Do! and Dig Dug. 26 years later, Digger HD has surfaced to give the classic PC game a new facelift for PSN.
