Some Intellivision games have known endings. Games like Utopia and Snafu have turns that run out. Sports games finish when the innings/periods/laps/etc. run out. Other games have a goal to complete such as Star Strike, AD&D, Treasure of Tarmin. You make the goal, get the win screen or you die.
What about games that just keep going. Are there any endings? Do any games have a mathematical limit? I'm talking games that go on and on like Space Armada, Astrosmash, Night Stalker, Deadly Disks, Shark Shark, Lock N Chase, Donkey Kong, etc. Do they stop at a particular number due to a limitations by design or other limitation?
