Honestly I thought Danganronpa was great enough for a go but be warned the game/writing has some very serious flaws.
-First and foremost, without spoiling anything, it has one of 'those' endings all too commonly seen in modern anime these days. The ones where the writer waves their wank in front of you and laughs because you expected explanations. Nope, gotta buy the sequel for that. It's not nearly as bad as the 'no ending' violators out there but there's a big enough chunk of the end game missing that if this is a pet peeve, do not play Danganronpa if you don't plan on spending a few days reading screen shots of D-2's English translation. (Or can wait a year+ for the sequel to be localized.)
-The Director for the game took the piss out on everyone and decided that somehow making everyone bleed cupcake icing would make everything scary. No, really, he's gone on record being quoted as that's why everyone bleeds pink. It really destroys what little horror atmosphere the game has because the set up, explanation, and cut scenes already (much more successfully) dive into the realm of visual absurd-ism. This choice might normally not be a problem, only here it proves to be a camel spine snapper on top of everything else. There are a few other smaller things similar to this but it's been too long to remember what they are specifically. I'm sure I'll figure it out when I play it through again.
-You must hold out for the Courtroom section in Chapter 2 for the game's cast to become likable. Unfortunately the writer forgot you need to have something to give you connection with characters rather than just writing a bunch a stock cliches; several of which are designed specifically to piss the player off simply because of how bad they are at surface value. Throw in motivations that are mind-numbingly stupid (without spoilers; the domino-tipping antagonist in the first chapter has a motivation so ill-conceived that I'm convinced they're actually suffering from some mental handicap in order to have sincerely acted upon it) and a very mixed message you get from the tale's theme-ing (The game tries to build horror; it really can't. The game tries to build 'realism'; but then chucks it in the bin 5 minutes later.) and you might be ready to throw in the towel before Chapter 1 ends, if the overall mystery isn't enough of a hook.
However late Chapter 2 enough cats come running out of the bag to fix most of those perceptions, flip things around and turn Danganronpa into a spectacular story with charming characters. It just has soooo much trouble getting that first foot through the door gracefully (humorously making it a bit like its central protagonist).
If you can get past those flaws though Danganronpa has one of the better main antagonists in a VN I've come across. Monokuma's not quite Beatrice levels of good but on par with Zero the III (and doesn't share his problem of vanishing after the first arc and never appearing again). The story might not have much of any horror to it but it more than makes up for that with entertainment value.
That, and one of the funniest still shot images I've ever been ambushed with to date.
Again, without spoilers, all I can say is "Shogyoken!"
