What I miss in many games today is an Endgame feature like Microprose used to do back in time.
They did an endgame page, Highscore/Hall of fame, that showed how well I did in past.
I could look at it anytime from the main menu.
This was especially fun than coming back after some time, doing a new career, and comparing what I did in the past and how it ended .
It makes it more fun then doing a replay and enhances the longevity of games I believe.
