Project Diva F2: PS3
i got both projec diva f's in a bundle for around 20 dollars off ebay. i think it was a very good deal! so glad the ps3 is not region locked!! i don't mind the language barrier since there isn't really any dialogue between characters, and the menu + gameplay is pretty straightforward. my favorite songs to play are: meltdown, kokoro, and luka luka night fever.
Project Diva F: PS3
very similar to F2. the only major differences are that F2 is a bit more polished, and they have different song selections. i did get surprised with this one though, since the DLC the previous owner bought somehow got carried over to my ps3?? not sure how that works but i was able to unlock some extra costumes + songs for free so yay!!
Project Diva Future Tone: Arcade
my favorite arcade game... so happy to see miku.. in real life.. anyways i really suck at this game. my skills from the PS3 versions unfortunately don't carry over. i can score a standard on hard, but i've only had the opportunity to play a few times because i don't want to spend too much on tokens lol. i like the star mechanism from the older games much more than the slides and holds in the future tone version. i hope i can get my hands on the ps4 version soon!!
Project Mirai DX: 3DS
a super cute spinoff of the project mirai series! the game uses models that are identical to their nendroid figures, which i really like. i don't play this one too often, but my favorite song has to be sakasama rainbow!
Project Sekai: Colorful Stage
the very first miku game i played. i remember being sososo excited for its release because it released at the height of my interest in vocaloid. i somehow managed to get a japanese apple id so i started playing right away. i've since then moved to the english version. i've been playing on and off since release. i don't pay much attention to any of the stories though. i just can't seem to get into any of the other characters that aren't vocaloids. i play on master/expert.
