Best cast, presentation, overall soundtrack. I think the end was a little funny, a tad confusing. Some mixed signals.
I think this is the best DR game.

This game is longer than it needed to be. None of the minigames are fun. Cases will bring up obvious reveals but through the lens of a slow taxi game, making plot points drag. Other times they will talk in circles in an effort to make class trials last longer.
The extra modes you unlock after beating the game are horrid. Just awful. I think the character interactions are cute and the idea doesn't seem too bad- IT'S BAD. If you fail to roll high enough to complete laps before time runs out, all of that progress is lost...? Who's idea was this?? Horrible. So much grinding you have to do, across multiple runs. Hard pass.
Also, every Danganronpa game has HORRIBLE audio mixing. It's impressive.

Fortunately I never played the game growing up so I had no expectations of greatness nor nostalgia to let me down. It’s a genuinely fun story with a ton of neat characters. A common complaint that I hear from others is that the combat was too slow and random encounters were too often, but they weren’t big enough problems for me to detract from the experience. The soundtrack is also one of my favorites of all time. I still use a ton of FF7 music in my D&D campaigns today. This game made a lasting impact on me and I’m super glad I decided to pick it up even 20 something years after it released.
