A strange little side quest
Even a quick game like Heroes Of War WebGL sits on top of decades — and sometimes centuries — of ideas. Games resembling checkers were being played thousands of years ago; evidence of related games reaches back to around 1600 BC. A second detail makes the picture even better: Early computer role-playing games helped turn rules, inventories, exploration and character progression into systems that could support long-form digital adventures. That history is one reason familiar mechanics can still feel new when they are recombined well.
