My copy-pasta P2 thoughts
I think it's a very good game that is unfortunately bogged down by its age. The best thing the game has going for it is its story which is a lot more involved since there's no social link system. A lot of a people say that P2 is "darker", it is to an extent, but it also knows when to introduce light-hearted humor. That being said the story of P2 can be very whatthefuck-ish but a little suspension of belief goes a long way. The P2 cast is fun and likeable, each member having his/her own character arc. P2 also has hands-down the BEST world of a Persona game. Sumaru City is populated by many NPCs each having a LOT of unique dialogue that changes VERY frequently as you progress through the story. I think I spent most of the game JUST talking to people. The only bad thing about the game is the battle system which is antiquated as hell. Demon conversations are neat though, this is also how you'll be getting tarot cards which you can use to fuse more personas. Dungeons are maze-like and confusing so of course the encounter has to be super high
The quality of the music is subjective but in my opinion it's not as strong as Persona 1 psp, though there are a few good tracks here and there.
But I still think its a great game, definitely worthy of the Persona moniker.
Plus the game has
THIS motherfucker in it(the ORIGINAL bro). HIS GUITAR CASE IS A MACHINE GUN
Regarding your P3 question, the FES version is available on PS3 as a PS2 Classic downloadable title. It's my favorite game of all time~
