I ocassionally work on one location and their arcade equipment. I was offered payment in the form of their Space invaders pinball machine in fair shape. I am a wpc guy otherwise and at more than full capacity (but there is always room for "one more" machine). Is Space invaders a worthy example of an A list title of that era (I know that Centaur, Fathom and Xenon are better) or should I skip it and add another game from that period? They also have FH (not interested in), Skateball, Zaccaria Moon flight EM and Taxi (my first choice but they are not ready to part with it yet).
