In general, open-source games are developed by relatively small groups of people in their free time, with profit not being the main focus. Many open-source games are volunteer-run projects, and as such, developers of free games are often hobbyists and enthusiasts. The consequence of this is that open-source games often take longer to mature, are less common and often lack the production value of commercial titles. In the past (before the 2000s) a challenge to build high-quality content for games was the missing availability or the excessive price for tools like 3D modeller or toolsets for level design. In recent years, this changed and availability of open source tools like Blender, game engines and libraries drove open source and independent video gaming.
At special occasions like the Holidays we pretty much blanket the walls of our house in Coloring Pages. In December there are pictures of Santa, Rudolph the Reindeer, Sleighs, Christmas Trees, Elves, Carol Singers and much more all over the house. While at Halloween no matter where you go in our home there will probably be a Pumpkin, Bat, Little Devil or Ghoul staring at you! I am careful to pack them all away carefully afterwards and intend to still be using them decades from now, much to the probable embarrassment of my son.
