Thank you for replying, I will have a look at the gamesI'd say definitely play it.
Danganronpa: The Animation (the anime adaptation of the first game) isn't very good at all. Too much story was jammed into 13 episodes and it just didn't work. It's all very rushed and flimsy.
2, V3 (the third game in the main series) and Ultra Despair Girls (a third-person shooter spinoff) haven't been animated, but references are made to them in the two Danganronpa 3 anime series (which are both good).
To get the full/best experience, I'd recommend playing all the games in release order (S/Ultimate Summer Camp is non-canon and not vital to play), then watching both of the Danganronpa 3 anime series (they won't make much sense without knowing what happened before).
There's a manga version of Danganronpa: The Animation available in English from Dark Horse, which is very good - that pretty much covers the first game faithfully if you don't feel like playing it. Manga adaptations of Ultra Despair Girls and 2 (two versions, from different points of view) are available too.
It looks like the Switch Ver. includes most of the games, excluding Ultra Despair Girls so unless they have managed to destroy the port then it might be my best option
