Innocents sin story gave me mental damage
Eternal punishments gameplay gave me mental damage

IS is braindead easy but EP isn't and it really shows the cracks in p2s gameplay when you actually have to try, its not the hardest rpg ever or anything if you have patience for the old school style grind kind of similar to p1, then you get a pretty solid game with, decent themes about adults who are still figuring themselves out.

It is kind of nice to show that stuff doesn't magically go away when you reach adulthood, as well as tatsuya being a mopey kind of nerd who was the one who couldn't let go it recon textualizes how he acts in Innocent sin and the fact hes still a teenager who doesn't know how to ask for help as opposed to the adults who also don't know how but know better.

Maya is very expressive but I really wish she could talk and have banter like she did in innocent sin especially with her roommate ulala who has a better relationship with baofu than she does with maya because baofu and her can talk to eachother and grow a relationship, baofu also has a great relationship with katsuya because their good cop bad cop approach is entertaining and they learn.

I feel the p1 fanservice is a bit heavy handed in this game and personally was handled better in innocent sin.

I guess I prefer IS but only because of a few things including gameplay, I want to say the party dynamic as a whole in IS is better since you have 4 characters who talk to each other while EP you have Ulala, Baofu and katsuya their interactions are insanely good and hit me when I didn't expect them but because the additional p1 party member is more for plot and as stated maya is silent and tatsuya really only gets connections during the end, it really is just 3 characters.

not a bad game though if you can handle the grind you'll love it
