First thing first, Devil Survivor => Devil Survivor 2. Maybe no gameplay-wise (then again...) Better plot, better characters, no friendship or Personaeque bullshit. True SMT plot. Heck, I even find the endings better, where you have everything you want. Though they kind of screwed up at some point, like with Keisuke, you can agree with his way of thinking, but in the end they still force you go along with idealistic craps.
I'm a bit of an odd with the 3DS versions, because while I do enjoy the voice acting... the bonus days are just weird. They just seem to linear and one-dimensional as hell, that it just... ugh.
And Record Breaker have a Golden Ending, which make cringe so much. As if Daichi's ending wasn't bad enough.
It doesn't mean that I don't enjoy them, but they just kinda feel out of place.
Oh boy, MagicMC is just badass !
Go if yourself Beldr, he is such and yet, it show us exactly what is Atlus, and why they are so awesome.
Fun fact, I names my MC Kazuya Toudou. Kazuya, in honor to one of the official name of the SMT1's MC, and Toudou in honor of the official name of P1's MC, which is Naoya Toudou.
See the joke ?
Speaking of Naoya, he is easily the best characters of the two games.
