C.H.E.A.T.

From Homestar Runner Wiki

C.H.E.A.T. is a game produced in 1982 by Videlectrix that is a parody of the Atari 2600 game E.T. the Extra-Terrestrial. E.T. featured an uncharacteristically detailed title screen and is often cited as one of the main causes of the video game crash of 1983.

C.H.E.A.T. appeared in an Easter egg in trading cards and unsurprisingly stars The Cheat; however, no more than the title screen has been revealed.
