no one who ever played a video game looked at someone else's score for any reason other than to determine how they could beat that score.
any score you make or do not make is irrelevant to everyone but you.
its another mechanism designed as a challenge something to beat or ignore at your leisure and it means nothing or everything depending on your point of view and interests.
maybe after playing for a decade you will look for new challenges in the rank system or score system if you enjoy it... say get rank 1 in every category... only 2 people have done it in aces high since 1999. their names don't matter to you only that the gauntlet of the challenge to do what they did better than they did it...
or throw the score out the window and make your own rules for what you want as a challenge... get 352 kills without getting killed. it may or may not have ever been done in this game... if you consider a streak to 299 then a death to ground fire a worthy but failed attempt to beat why not go the full monty and spend a decade trying to hit 352 every month since 1999.
or better yet throw all statistical satisfaction of aerial digital combat mastery out the window and go for shear fearlessness and take every fight no matter what and win against the odds until you do it so often it literally takes 5+ to kill you most fights so you fly in low and slow outnumbered 10 to 1 and die nine times out of ten but on that tenth glorious try you kill all 10 and land your smoking wreck of a cartoon airplane on the digital tarmac and cant contain your excitement about having captured this epic run on fraps to live for all time on you tube to view at your leisure as the best fight you ever had... so good that you simply see no reason to even play again because this was as good as it gets and then you go play something else until the bug hits you and you have to try it again after you forget everything you ever knew about cartoon air combat.
