Was literally talking about this with a friend yesterday.
Depending on the game you could see if it has a journal function of some sort that serves as a reminder, or perhaps an extras area where you can watch unlocked story sequences. (All story driven games should have some sort of reminder system IMHO.) Other than that watching some Let's Plays could help jog your memory.
Barring all that I have just started playing a game again and the story slowly came back to me as I continued to progress. In a few cases I totally started the game over from scratch.
