it's literally persona 5 chapter 2 (the original ps3 version though, no mention of p5r added charaters and portraits are from the original game)
the musuo genre didn't make this game not feel like you are playing persona, it is a great twist on what live action persona can be, super fun

It depends on 'why' you liked P5R. If you play Strikers with the same expectation you had for Royal, then you're bound to get disappointed.

The plot of Strikers is a carbon copy of Persona 5 (the base game, not Royal as mentioned by P. Dimi). There will be no Kasumi, no Maruki, no Akechi, and everything that happened in the third semester is deemed non-existent.

But if you don't mind the musou genre and want to meet the new characters (I personally love them), then I recommend getting this game when it's on sale.

No its not. From the first hour of playing I was not interested. Its not close as emotional and impacting or had the same high stakes story like P5. Ended up watching the cutscenes and plot on youtube and that was a waste of time too. P6 if it ever comes out better not follow the same misdirection this game went into. This game had no business being made
