Yeah, a lot of people liked to say how DR2 was dramatically better than its predecessor, but I do not think so. Overall, I think I preferred DR2 slightly more because the classroom trials and cases were that much more engaging, but DR1 also had better qualities such as its novelty, its music and its setting.
I'm surprised that you feel way.
To me, SDR2 is a huge improvement DR1 on just about
every aspect, to the point where I'd sooner replay SDR2 twice before replaying DR1 once. The graphics and art design were much better. Character sprites were much better drawn, backgrounds were more distinct and vibrant, and each location stood out. I know DR1's setting lent its the atmosphere, but a decent amount of locations felt samey or unremarkable.
As far as gameplay is concerned, it's a 4 steps forward, 1 step back kind of a deal. Little things like being able to agree with with others and support their arguments went a long way towards mixing up the trial flow. The new minigames were hit and miss, but personally I liked the snowboarding minigame, found the new anagram minigame to be fun (but I concede that going for a perfect on higher difficulties is a huge pain) and I adored showdowns. (Seriously, showdowns are fucking awesome if you had the right skills) Oh and skills actually served a purpose this time around. They were actually pretty diverse (too many of the first game's skills were useless or redundant) and more *fun*. Generally, the pacing for each trial was much better in SDR2. There's less stupid nonsense overall (remember the "Kyoko is a ghost! testimony?") and far less padding (see Chapter 6's trial). SDR2 also benefits from the fact that the first chapter is fully-fledged chapter, whereas DR1's first chapter was a tutorial.
In terms of characters, SDR2 is super duper despair-inducingly better than DR1. The problem with the DR1 cast was that most of the characters simply did not have enough time to stand out. Most of their development was found in their FTE, whereas the SDR2 characters get development in the main narrative and the free time events, so it was like having 2 big scoops of icecream for the price of one. And honestly? Pound for pound they're just much, much
better. Hajime >>> Makoto, Nagito >>> all of the DR1 antagonists, etc.
A big thing set SDR2 apart from DR1 in terms of characters was the presence of a "rival character. "DR1 didn't really have a rival character. At least, nowhere near the same extent as
Komaeda. Komaeda completely, completely changes the dynamic of each chapter. He added a ton of tension and intrigue to each trial,
by himself. In terms of supporting protagonists, i'd argue that Kyoko 's presence (while awesome) ended up being slightly detrimental, because there was rarely a point in the game where you felt were forging new ground. Many of the conclusions Makoto reached were also reached by Kyoko. You ended up feeling more of a helper than an actual sleuth. On the other hand, Hajime comes up with many of the major deductions by himself, and while Chiaki helps out tremendously, it never feels like she's setting the pace for the trial. Junko is much better in the second game, and her defeat felt a lot more satisfying.
SDR2 isn't perfect, and it suffers from many of the same flaws as the first game, but damn, it just makes the first game feel downright underwhelming by comparison. It really earns that
Super prefix.
