Do you have any games that you have hit a roadblock with near the end whether that be completing the game or getting the plat/ final achievements

I was looking through my games and noticed that I have a few with well over 90% completion but not finished, an example is GOW where I have done everything but defeat the Chief Valkyrie another is Persona 4 golden where getting the last Fish stopped me I ignored it and completed the game knowing that if I went back it would only be to get the plat , now some games  don't worry me because I either completed the game story wise or was never interested in doing a 100% anyway but the ones that have me in two minds are the ones that I gave up on due to the frustration of getting so close but at the same time sick of repeating them , what about you guys?.
