A screenshot from an "event scene" in a video game. To be a game CG it should not include text boxes, character sprites, or game menus. It usually comes from a visual novel/eroge, but can be from any type of game.
Mass CG uploads are generally not very interesting, as 90% of in-game art is completely bland and featureless, with very little originality by design.
