Answer:
Themes
Step-by-step explanation:
Good stories usually have engaging themes that pertain to a certain interest, group, or fanbase. Video games have tackled everything from the end of times to meta 4th wall breaking and self awareness. As long as it has meaning to you, that's what matters.
But as some examples: Ruin and rebuilding (maybe something pertaining to city building? Fantasy?). Creative process (a game about making a game?). Or maybe a dog petting simulator with soem deeper meaning behind it about the joy from compleatings dull tasks? Whatever.
