2 versions of this one, wasn't sure which to enter but I decided to put in the accurate one.
Created with a mix of MS Paint and a program called GraphicsGale. "Find Edges" effect applied to the second one in GraphicsGale.
All of it was hand done by myself, using screenshots from classic games for reference guides. Accuracy was the aim.
Games from left to right: Pong, Adventure (Atari 2600, ownage game, first game to feature an easter egg), Space Invaders (Would be original PC version...the 2600 version had a more detailed gun turret), asteroids.
