a game which is slightly less that average
Like an arcade game from the late 70's with great graphics or an arcade parody from the 90's with bad graphics. take you pick.
There are no goals other than getting a high score, and after playing one game, there is no reason to play it again.
The only reason I can see for playing a game like this, is to pass the time until the microwave oven says 'pling' and you can eat.
