SMT: DDS threw some light upon some existential thoughts I have had all my life.
Played this one after it's sequel.
For me this showed how a good JRPG can be. Excelent combat mechanics. E.g. exploiting enemy weakness doesn't give excessive advantage. It cost MP with cost gold to restore. And gold is also used to buy skills that you have to train before being able to use.
Bosses are challenging.
The story is :cheff_kiss:.
And the soundtrack fits really well with the mood of the game.

Spoilers:
Gale's awakening is one of my most precious gaming moments.
