there's some cringe queerphobic shit in shinjuku iirc, and lala-chan is in some regard a stereotype but not an especially problematic one (imo)

there's a (somewhat spoiler-free) 100% walkthrough i could dig up if you ask nicely :P

edit: i found it for you anyway https://psnprofiles.com/guide/11946-persona-5-royal-100-perfect-schedule read at your own risk! most of the story stuff is spoilered/absent but be careful to not click that spoiler shit til you're ready, and the guide is pretty much "just say this" to the confidants, so idk if you'd be into that. also the boss names are all available so you might not wanna read that either.

Go whole hog on the pokemon and fusion aspects. You can make the game trivial very earlier.

Hang out in a spot and enjoy the vibes, especially when it’s raining, the atmosphere can be very cozy.

Finish every dungeon in a single session once you get the option to, you’ll want to maximize your amount of time out of dungeon if you’re trying to max as many links as possible. This helps with the lack of difficulty by making resource management more engaging.

save daily, once you run out of slots try and keep like a Monday and overwrite to the next Monday in case you need to go back in hindsight. If on pc, you can get around this by backing up the save files somewhere else before overwriting.

All of that being said, the game really is at its best if you can overcome/ don’t have a completionist mindset (so ignore most of that if able).

I wonder if they put as much queerphobia in this one as in Persona 4...

You should find a spoiler free relationship answers spreadsheet. Otherwise you won't get all the relationships done and you will probably miss the true ending because you said the wrong thing at the wrong time. It's super infuriating. But there are spreadsheets out there that are basically like "using this spoiler free code name that will make perfect sense when you get to that part, choose option 1 then 3 then 1 then 1 then 1. Etc. super helpful very recommend

Exploiting enemy weaknesses is pretty key to winning on the RPG side of it. It's not a particularly difficult game, though, so I think it's best to just sit back and enjoy it.

There's a special ending for the Royal version that requires maxing out particular characters social links. Don't worry if you don't get it on your first playthrough, you can easily play New Game + and get all of that.

The mastermind villain being a Shinzo Abe stand in is funny
