Authors of books, scrips you name it they all have a plot unless it is a chick flick. Which has a borefest instead.
Authors often have a conflict in there peace, some times it is man vs. man another time it could be completely different like man vs. nature or man vs. himself and it could be man vs. society. some times the plot can be classed under more then one of them like man vs. society and man vs. man could go together if there was a battle or a struggle my point is that there is an endless number of plots an author could put on his blank page and because of that there are many peaces of work out there that would not be there unless there was man vs. man or man vs. ect or whatever vs. whatever.
Two examples of man vs man are Eragon and Battles BC
