I was looking at the gamefaqs guides to get some quick info on Shining Force. One of the walkthrus indicated he played thru 20+ times to try and get different results.

dear lord.

I couldn't even play Silent Hill thru the second time to try and get a different ending. I just lose interest once the game has been beat.

I'm only talking about games that are 1 player, not online, and have an ending. So games Mortal Komat,Halo and Phantasy Star Online do not count.
