This game franchise is literally just a take on the age-old question of “Which character would win in a fight?” Fighting games are usually profitable. Nintendo characters are icons in the industry, regardless of how long you’ve been a gamer. And much like the superhero “who would win in a fight” debate, the same thing has existed for Nintendo characters as the NES game library grew. While it was only a matter of time that such an idea would come out and would work, when the original Super Smash Bros game came out, it was a weird novelty that happened to work out and succeed.
