Completed Persona 2 Innocent Sin.
I haven’t mentioned the dungeons in Persona 2, and that’s because they are horrible. They are ugly mazes that lack any logic and made to be annoying with invisible traps that often impossible to avoid. Xibalba, the final dungeon / alien spaceship, is the epytomy of everything wrong with them. It’s 8 floors of annoyance.
Storywise, it’s a fun concept, though, were all the fears come true. So when one character says that there might be laser traps, and another is afraid to be locked in an oven room: both things happen. And Michele has to face metalic version of his father, because that’s what he’s afraid of.
I managed to beat the final boss with the default personas, and my characters were only around level 57 or so. So I honestly thought there will be another dungeon after that.
The ending is disappointing, and it feels to me that they just decided to split the game in two. After beating Niarhalotep, Crazy Teacher appears and stabs Maya with Longinus spear, so she cannot be healed. Nia says something along the lines, “what did you expect, to beat a god and defy a profecy?” and Philimone offers to “try another time”. This is a common theme in Shin Megami Tensei games, where at the end heroes are offered to either forget everything or continue suffering: Persona 3 and Devil Summoner 2 are two examples I remember, and I didn’t play that many games in the series.
