I started with Persona 4, then I played P3P. I have yet to try P2, but I intend to. Also have a copy of Nocturne waiting to be played.
I like the S.Links, I like the 'dating sim' portion of the game. I like fanservice parts because I think they're cute.
I still spent over 300 hours playing P3P, and about maybe like 200-250 playing P4, over several playthroughs, and most of that was spent in dungeons grinding or fusing.
Sorry if I'm the kind of person that Atlus is catering to and that's ruining your game, but fuck you if you're trying to say I have bad taste. I'm not going to be somehow morally offended because some pixels have an associated age in a made up story game and I find them appealing. I'm also not some mindless plebe who is only drawn to these games because of -whatever label you want to use - "otaku" elements.
I'm honestly kind of sick of reading all the crap from SMT purists who are upset the games have gone away from what they originally were. I get that these games are drifting away from what you originally appreciated in them, but that doesn't make the people who enjoy the newer games any LESS than you. Whatever justifications you have to tell yourself to feel that way aside, don't take it out on people who are receiving new games that they can enjoy!
