No matter how you cut it, playing the same level over and over because of no in mission saves is frikkin boring and a definite reason for not finishing a game. Limited mission saves suck just as bad a la Splinter Cell which I got in January, and have to this day not completed due to only be able to save at check points which generally come after a difficult part has been finished. SOF2 actally had it right. If you wanted you could limit yourself to 5 saves per level, or you could have as many as you wanted.
