Probably the biggest difference between all these arcade games and their NES counterparts are the lack of cut scenes. NES Mario doesn’t have the “how high can you get” screens. Donkey Kong Jr. is missing cut scenes and animations. Mario Bros. is missing explanation screens (and the levels are different in the home version, such as the game opens with three turtle waves while the home version only has two before the bonus stage). It makes me wonder why they couldn’t do these things on the NES. The NES went on to do impressive things graphically. Well, I found out that it was a cost-cutting thing. Back in 1983, every KB counted.
