I LOVE PJ SEKAI (its a very good rhythm game plus if your a miku fan most songs you like from miku are already there) From my experience in the jp server i'd say its more better than the global servers just imo i have the global version too
In the jp server they add new songs more quicker than the global servers most songs on the jp server are not on the english version of pj sekai yet, BUTTT they are coming soon you just have to wait a VERY long time

Rewards in the jp server treat you better plus there are tons of new events that arent in global (yet) there are more cards on the jp server too :) most of the four star rui cards i want are on the jp server anyways :P
As for gachas try not to spend too much crystals if you can ;---; proseka has A LOT OF BEAUTIFUL CARDS ESPECIALLY RUI COYSJAJAJ, but its best to sometimes resist the gachas so you can save crystals for an actual gacha thats worth it or one that you've been looking forward to (like the color fest gacha) color fest gacha or the anniversary gacha is truly worth it plus if theres a certain card you want no problem im pretty sure color fes gacha will give you it
OH YEAH SONGS, most songs are a bop very catchy 10/10 but there are some that are difficult to full combo on master like jinsei and whats up pop
im always up for a challenge when it comes to rhythm games but GODDAUYM MY THUMBS HURT FROM THOSE SONGS, for master players i would pratice with songs that are from at least lvl 30 or lvl 29-28-27 before trying one of these hell songs 

anddd thats it for my review if your a beginner at rhythm games i highly recommend playing bandori or proseka, thats all and remember rui kamishiro is a snoobert

5.0Everyone in these reviews seem to be filling it with word spams, so I'll give an actual review for anyone if they see it. If you are looking for a rhythm game that involves tapping a screen, and has vocaloid covers/music, you are in the right place. This game has a very good rhythm game inside of it, with tapping that usually registers and with challenging charts as you move up the difficulty. The difficulty does spike I think between hard -> expert but it is just a matter of moving up levels slowly (or brute forcing it like my sister did, but I digress). The rhythm game is a very nice experience on both mobile and tablet, but I believe a tablet is better for the harder difficulty, however you should take that with a grain of salt as that is just my opinion! Playing on a wide phone is not a pleasant experience for me, since I have small hands, but playing on a phone is not a bad experience or anything, I believe the game does work quite well. The characters in this game are very well-written in my opinion, even the characters you may grow to not like. I personally don't really like Mafuyu as a person but her struggles and her character, for what it is, is well-written. The 5 groups in this game all have their each seperate story with 20 episodes in it, which you unlock by playing songs with cards of the characters in their respective groups, or by reading area conversations in the overworld. The episodes are not very long and give a good introduction of each group and character individually, with the event stories then developing each character with their respective struggles and dynamics with other characters. There have been many events so it is quite hard at this stage to read all of them, I would recommend to read the main story of the group you like the look of the most, and get to know those characters. If any of them appeal to you, then you can read the event stories surrounding that character. There are also side stories for each card which can be unlocked using in game items, so if you are interested in a certain character, these side stories are a good way to know them better. The gacha system is also alright, it is easy to tell whether you have a 3* or 4* based on colour, 3* means yellow and 4* means purple. The indication of a "flip" is also shown clearly, with the floor that Miku steps on turning into a purple circle instead of rainbow or the floor becoming transparent with the purple circle. The rate of a 4* being 3% isn't that bad in my opinion, and there will be occasional Dream Festivals, where the 3% becomes 6%, with special limited cards as well. The cards in this game are also very well drawn, they have a consistent anime style and are very high quality. In JP, as of August 2022 when I'm writing this, the cards have been slowly implementing a newer style with the anime style, with nice colours and illustrations. The card quality in consistent throughout all 4*s and even the 3* cards are still very nice to use if you don't have a 4*. Grinding for crystals in this game is not bad once you know where to look, (I'd recommend looking up some youtube videos before you start) and in the early game it is very rewarding, however once you reach Rank 50 and have played most of the songs with full combo's, crystals become much harder to get. It takes much longer to rank up and playing songs you don't like doesn't appeal to many people. Fortunately, in the JP version, the music library is much vaster than the Global version at the time of writing this. If you want a version which has newer events, more songs and a more updated game, then I would recommend the JP version. Even if you can't speak japanese, there are probably translations out there for the game, and the UI of the game isn't that hard to understand. If you don't want to play the game because of the language, then the Global version is for you. It is currently catching up to JP in events but it has many songs and gives you the same experience. There are many instagram accounts that regularly update and post about Project Sekai on both versions and there are youtube guides out there in case you are confused or need a preview of the game. I hope this review helped! ♡

5.0I'm going to be making a lot of comparisons to Garupa, also known as Girl's Band Party, because they are very similar. For being one of the first mobile games featuring the Piapro characters that I've ever played, it's actually really good. It introduces a few new human characters that are all interesting. Pros: Gameplay is similar to Garupa's, so if you played it you have an advantage. One difference is the notes, you can't really change the size of the notes in Sekai, and the notes vary, they can take up the enitre lane or be really tiny. Another is the character ranks. By reading area convos and playing, you can increase character ranks as well. The game has five difficulties, Easy, Normal, Hard, Expert, and Master. The game can be played by casuals and hardcore players. So don't worry too much about game difficulty. Song list is actually very diverse, and include popular producers and some who are not as known. Mikito-P, MitchieM, KZ, Kemu, Mafumafu, Junky-P, Nero, and other producers have songs that are featured in the game. They also were nice enough to include songs from other Virtual Singers The characters are all really interesting and the voice actors are really talented. The covers are great, and I actually enjoy playing with some of them. Not to mention they're all really unique, so I'm sure you'll find a character you'll like. There seems to be constant events in the game, just like Garupa. So there will always be something new to grind for, if you're into that. The graphics are great, as excepted from Colorful Palette. The characters look so pretty, especially my husband Kaito. The chibis are also really cute. Gachas are a bit more expensive, than Garupa. But they make up for it by being very generous. Reading convos and increasing character ranks are very rewarding. Cons: Grinding in this game is hellish. Training/practicing characters is a difficult grind to do. I don't mind it, because I have little 3★ and 4★ (not because of gacha rates). Ranking in this game is also very difficult. There are about 20 million people playing this game, so obviously ranking is going to be tough. Rewards for ranking are decent, top tens usually get enough crystals to do one pull. The tunning for the Virtual Singers can be very choppy. I'm sure they tried, but it sound super off sometimes. The cover for Fragile using Len and Kaito sounds weird. And Meiko sounds too soft in Hibana. It sounds good in other cases though, like Kaito in Dappou Rock. It could be tuned that way for the human singers, but it's not fitting sometimes.
