...mmm.... In Mike Tyson's Punch-Out, getting 5000 points declares you the winner if you haven't KO'd your opponent, but in Star Tropics, I have absolutely no idea what the points are for, or why you only receive them after beating a dungeon. I do know that Sonic games typically give you an extra life for every 50,000 points you earn, and that Mega Man 1 seems to be the only game in the series that gives you points for doing anything (and even has a "Best Score" randomly determined at the start of each stage). Most arcade games give you free lives at certain point values, but that was before games had major collectibles in them.
Man, who'd have thought points would spark such a chain of thoughts?
