Games with sparse saving features. I really don't see the point of "save points", but they aren't always intolerable. However, then there are games like Luigi's Mansion Dark Moon where it saves at the end of the mission. The game seemed enjoyable enough, but when I got stuck on a long mission and just wanted to turn it off and give my eyes some rest I had to turn it off, lose everything I had done in that mission, and haven't played it since. =/
