Because very cool
Though, it will take up most of your storage since they added world exploration or however you call it to the game. Since it's pretty new, there isn't much to do in it right now, but there are a few quests you could do if you plan to, they only added the feature about a few weeks ago and finally added a female MC which i'm happy about, (I support lesbianism so which is why).
On mobile, PGR only takes up 20-30GB of storage (unsure since i never tried PGR on mobile), while on PC it takes up about 50-60GB
The Graphics are nice, they're so good that i have to put mine to the low so i never really experienced high quality, the music is nice and i suggest you listen to 'I Always Do' and 'Lamia' by Ghostfinal and others music, with that 'Dancing Tonight' will still be my favourite.
The story is enjoyable, but. I did skip some because i was speedrunning the game and all, and i really enjoy earning to get characters, speaking of characters, it is best for you to join now since there is a limited banner up which is Liv: Limpidity, her design is nice and i'm building her since i plan to use her as a main in my teams.
Her banner will be in the game until Dec 22nd.
i started back in April 15th this year, i haven't really been active since i've been kept busy with other games that i play and schoolwork, so there might have been new features that i didn't know about.
