Danganronpa 2 does a lot of things much better than its predecessor, but also does a couple of things slightly worse. Overall, I think its a great sequel that did its job as a murder mystery better.
- There were less characters in this that I hated. Everyone in Dangan 1 was a certified weirdo, but this cast comes across as humans with quirks instead of straight "This is my one and only character trait." There were also more characters competing with each other for the position of my favourite, whereas in 1, I only really liked Hina and Sakura.
- Nagito's existence alone earns the game half a star. Such a compelling and interesting character that really brings a new element to the story of a murder mystery.
- The longer trials are both a blessing and a curse. It allows more complex trials, but the extra complexity of most of those trials comes from an extra red herring or everyone umm-ing and aah-ing about fairly obvious evidence. Some of these trials are over 2 hours long. I'm tired, man.
- "Improved" hangman's gambit
- Trial 2 is my least favorite trial so far, as I was ninety percent sure of the culprit, only to find out that I was wrong and that the real answer was much dumber. But the game made it up to me, as I was then able to guess the culprit for the remaining trials (This is not a bad thing. The shock value still remains and it makes the player feel smart)
- On the topic of trials, some of the leaps in logic this game expect you to take are laughably bad, and I had to consult a guide at points, as numerous truth bullets could refute a statement, but only one fulfills the very specific line of reasoning that the game doesn't tell you it wants.
- The setting of this game is also generally better imo than that first, with better variety and cooler set pieces. Monomi was also an addition that won me over.
- The executions in this are so extremely massively underwhelming except for two.

An absolutely phenomenal game. I finally got to play this on a decent PC, and I am so glad I could, as this thing looked beautiful and was so much fun.
The combat is intuitive and dynamic, and is everything that FFXV was missing. Being able to switch characters whenever you want as well as issue commands to the members you are not in control of is the best mid-way point between the ATB system and modern action gameplay.
I watched a Let's Play of this whole game a few years ago, as I thought it would never come to PC, and there were a few sections in that that I thought dragged on for way too long and didn't need to exist. Actually playing those sections though, there's only one chapter that drags (And that level is Hojo's laboratory. All my homies hate Hojo's laboratory). All the sections don't seem as long, because the gameplay is so fun that it distracts from how far away the goal is.
This is also one of the best usages of summons in the series, because they actually feel as if they do something meaningful and are not a pain in the ass to activate.
The materia system is as good as it was in the original, even if I couldn't find the Enemy Skill materia. There's even some new materia sprinkled in there, all of which feel warranted and well-balanced.
I also cannot overstate just how cool this game feels. Everything is so cinematic and smooth. This was the second time I ever used photo mode in a game, and let me tell you I got some magnificent shots.
I only had two minor gripes with this game. The first was the sidequests. They aren't all that gripping to begin with, and the overall quality of the dialogue and character models dip noticeably during them. They were well-implemented into the narrative, and I didn't hate doing them, but they just felt as if I was watching a cutscene from Lightning Returns.
The other gripe is not actually with this game specifically and more so where Square might be taking the series going forward. This game is not just a remake but also a sequel to the original in a way, and I feel that a lot of players unfamiliar with the original game or Crisis Core may feel as if they have to go play all of those in order to understand these remakes. I honestly wouldn't mind if the trilogy is just a one-to-one remake of the original just with better graphics. I also didn't mind the new additions to this entry. I just do not want Rebirth to end up as some completely different game that looks nothing like the original just because fate has changed its course. Let me see all the dumb stuff from the OG, Square!

The DLC is fine, if a tad too long. I am way too good at Fort Condor, and Sonon is probably the slowest party member in all of Final Fantasy.
