Darkness represents the sin of mankind. John 3:19 20 ESV. And this is the judgment: the light has come into the world, and people loved the darkness rather than the light because their works were evil. For everyone who does wicked things hates the light and does not come to the light, lest his works should be exposed.

Darkness is open to interpretation, since it's defined as a lack of light. There's also a figurative darkness, which can represent wickedness, sadness, ignorance, or simply mystery: "The details of their adventures would remain in darkness, unless one of them wrote a book someday."

Insaniquarium is a 2001 virtual pets simulator video game, developed by Flying Bear Entertainment and published by PopCap Games and MumboJumbo. Before PopCap Games's involvement, the game was a web-based Java game released in 2001.

The first real game on Facebook was "FarmVille," which was launched in 2009 by the game development company Zynga. It quickly became one of the most popular and widely played games on the platform, allowing users to build and manage their own virtual farms.
