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.

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.
