Background Graphics

Here is another post for my graphics assessment, this time it's:

Background Graphics:

Background graphics are essential to any game, without them the sky for the game, the forests or the clouds, would all just be a black space, a lot of games use concept art for backgrounds in the distance, instead of adding more polygons which would increase the rendering time, games need background graphics to add a feel of realism to the game, it's not just a blank sky up there, there's clouds, the sun/ suns, birds, freaky bird alien things, whatever there is, in games, there should never just be a blank background
