Let's teleport back a whopping 42 years... Boulder Dash is an action-puzzle game released in 1984 by First Star Software. You play as Rockford, a miner, digging through dirt to collect diamonds while racing against a time limit. Sounds simple, right? Well, the concept might have been simple, but the difficulty level ramped up quickly and you need real skill to play it. The genius lies in the realistic physics: boulders (and other objects) stay put until you remove the dirt beneath them, at which point they fall, potentially crushing you or enemies. You must strategically dig paths, drop rocks to kill enemies or create new diamonds, and reach the exit without getting squished. The game's title was a pun on "balderdash" (meaning nonsense). It's one of those rare timeless gems, maybe not quite on the same level as Lode Runner or Pac Man, but I'm sure that you played Boulder Dash if you were a gamer in the 80s. In 2011, Boulder Dash was included in the Smithsonian's "The Art of Video Games" exhibition, to highlight what 80s gaming meant.
