Witcher 3, played about 5 hours but the game seemed like it wanted me to look up the monsters I was hunting in the bestiary and then craft potions etc to counter them and I couldn't be bothered with all that. Then when I played it again, on the same difficulty as before, I found it way easier for some reason, and didn't need to bother with any of that.
Ocarina of Time, played the first 4 hours of the N64 version about 3/4 times over the years and never got any further, then a couple of years ago I played the 3ds version from start to finish and loved it, 18fps on the n64 was killing it for me.
