There was an Alf game for either NES or SNES and it was horrible it had no instructions and nothing really happened none of the buttons really did anything and after 15 seconds or so the time would run out and you would lose it was very frustrating :P oh and not to mention its horrible sounds and graphics as for ET I've never played it so I'm gonna have to go with Alf :P
anyone remember that Cap'n Crunch game that came in the cereal probably like 5-6 years back(Cap'n Crunch's Crunchling Adventure) .. That was atleast 5x better then half of all the games ever released :P I can imagine this thread getting very popular with unsatisfied people xD
