I tried Dx2 recently and finished the first chapter. Despite usually loving SMT's core gameplay and the game being basically a streamlined version of that, so far the whole experience has been really underwhelming. The game feels more like Digimon Cyber Sleuth in tone and narrative than SMT proper, no meaningful dungeon crawling means half of the series' appeal is lost to me (I know there's something like that later on but I haven't unlocked it yet), difficulty is too low right now, the story and characters just aren't compelling. The whole game doesn't feel like SMT and so far it does nothing any other modern installment doesn't already do better.
It's fine if you're craving for that SMT fix, have already beaten all the other entries and want to try something new, but to me it just feels like a wasted opportunity. If the game was more like mainline SMT and you could actually choose your alignment, there were events where each faction competes against one another, and the whole thing was a multiverse/amalaverse coalition of all the titles in the franchise and you got to see Aleph, Demi-Fiend, Stephen and other recognizable characters from all over the series in a plot involving the grand war against the Great Will hinted at in Nocturne, then it'd be a lot more interesting to me. As it is I'll probably just play a little more to see how the dungeon thing works and what the more difficult content looks like and probably delete it from my phone after that.
