this one i had rolling in my head last summer but i didnt make cuz its mostly a story game and i cant do story games:
you're a kid who has to organize your dads files (meeting minutes, receipts, project folders, etc.) your dad doesnt talk much so you dont know much about his past, but you learn bits and pieces about it from these files, out of order. some of it tragic, some of it funny, and then basically the idea would be that you fit it into this timeline that describes your dads life before you were around.
there might be some aspect of 'i need to get these files organized before this specific time' as well, just to limit how much you can learn from a particular document before you have to file it away
