Nobody is happy about the current state of our COVID-ravaged education system. With a new school year fast approaching, plans for teaching students still in flux, and political in-fighting driving more fear and confusion about whether or not to re-open campuses, teachers and parents are concerned. Meanwhile, most kids are just fine with spending less […]
Creating a fantasy world for a video or role-playing game is tough enough. In addition to all the game framework and functionality that goes into a build of any size, creators invariably sweat over the most minute details of every weapon, outfit, or other distinctive objects in their game. Even if your game is set […]
