Boulder Dash is an old game, which was originally created in 1983 by Peter Liepa and Chris Gray. The hero was named Rockford. He digged underground to get the diamonds without getting crushed by boulders or obstacles.
Today, we no longer plays necessarily Boulder Dash, but the concept was kept and developers regularly releases new games in which the hero has to go digging for diamonds in the ground without getting crushed or buried.
Boulder Dash is not going to be forgotten!
