What is NOSTALGIA

What is ノスタルジア?

A ノスタルジア cabinet.

ノスタルジア (romanized as NOSTALGIA) is a piano based touch music game released by KONAMI on March 1st, 2017. It was first announced on February 2016 during the JAEPO 2016 event. Although ノスタルジア was not advertised as a BEMANI game at first, it was later added to the BEMANI family of games at subsequent location tests.

ノスタルジア's machine serial number and version ID start with PAN.

According to sound director wac, ノスタルジア is meant to be both a "piano game for those who do not play piano" and "a BEMANI game for those who do not play BEMANI".

ノスタルジア runs on a modified BeatStream cabinet, although a dedicated cabinet (which lacks the upper screen) is available as well. The piano design of the cabinet changed several times during the location tests, although the piano design on the final cabinet resemble to that of the first location test (white and black keys, but only the white keys are used for gameplay). ノスタルジア is keysounded, but "extra" sounds do not play if there are no notes present.

Game Modes

Two game modes are available at the start of your credit:

• STANDARD mode: Can be played with either regular credits or PASELI. This is the regular play mode, Normal and Hard charts are available, while Expert charts can be unlocked by clearing Hard charts with an A grade or higher. Real charts can be purchased with the in-game currency nos.
• FORTE mode: Expert and Real charts are available by default, and items in-game can be obtained more easily. In the Korean version, this mode requires twice the credits of STANDARD mode.

The availability of the modes is the following:

Country	Cabinet Version	Availability
		STANDARD	FORTE
Japan	Japanese	Yes	PASELI only
Korea	Korean	Yes	Yes
Other	Asian	Yes	No

Gameplay

Much like the KEYBOARDMANIA series (or even more similar to Rayark's Deemo, VOEZ, and SEGA's CHUNITHM), players have to hit a piano key while the scrolling down notes reach the judgement line, located on the lower screen. However, players do not have to hit the specific key on the piano to match the note on the screen. Instead, hitting the key(s) surrounding the scrolling note is sufficient. On higher difficulties, fewer surrounding keys count toward a correct note "hit". Hits can be judged as ◆Just, Just, Good, Near (introduced in FORTE), or Miss.

Three difficulties (Normal, Hard, and Expert) are offered for each song, although in the JAEPO 2016 location test, each song had only one difficulty. A fourth difficulty, Real, was added in ノスタルジア Op.2.

Notes with a red hue are meant to be hit with the right hand, while notes with a blue hue are meant to be hit with the left hand. Certain songs will "suggest" that players cross their hands over.

Besides the basic notes, there are three types of special notes:

• Tenuto: A long note, much like hold notes on other BEMANI games.
• Glissando: A slide note across several keys (not present in some Real charts).
• Trill: Similar in appearance to a tenuto note, it has to be hit with two adjacent keys on a quick sucession.

Gameplay options

The following options can be set after selecting a song (but before playing it), by touching the "Option" button on the screen:

• Headphone Volume: self-explanatory. The value set by the player will be kept during the credit unless the headphones are removed.
• Notes Speed: you can change the speed at which the Notes flow from 1.0 to 3.0, with 0.1 increments. In the left part of the screen, you can preview the speed of Notes set by the player.
• Judge Timing: allows players to adjust timing from -5 (early) to +5 (late). Introduced in FORTE.
• Judge "NEAR": toggles ON/OFF the NEAR judgment. Introduced in FORTE.
• GUIDE: toggles ON/OFF a metronome which sounds on every beat of the song. This option can also be toggled during gameplay by touching the small metronome icon on the screen.
• Both hands / Left hand only / Right hand only: by selecting the "___ hand only" options, the notes on the side of the hand you did not select will be played automatically. This option can be selected on the difficulty level selection screen. A song that has been cleared for the first time by selecting one of the "___ hand only" options will have a mark next to the score, and Full Combos with these options will not be counted.

Additionally, players have the ability to lift or lower the judgement line (including the on-screen piano guide area), from +20 (high) to -20 (low). Note that this does not change the timing itself. This option can be set during gameplay from March 22nd, 2017 onwards.

Scoring

The game does not feature a life meter. Instead, similar to the jubeat series, a minimum score of 700000 points is required to pass a song. Failing a song does not automatically net a game over, regardless of the mode you have chosen.

When the song is finished, the player will receive a score up to 1000000 depending on his/her performance, and will receive a message depending on whether the song was cleared with Perfect Performance (full combo with 1000000 points), Full Combo, It's Fantastic (regular clear), or Finish (fail).

Judgement point

Let N = Note count
Let J = ◆JUST count
Let j = JUST count
Let G = GOOD count

Judgement point = 1000000(J+0.7j+0.5G)/N

NEAR (introduced in ノスタルジア FORTE) and MISS give 0 points.

Rating

Ratings will also be assigned based on the score:

Rank	Score
Pianist	1000000
S	950000 - 999999
A+	900000 - 949999
A	850000 - 899999
B+	800000 - 849999
B	750000 - 799999
C	700000 - 749999
-	0 - 699999

e-amusement

When used with an e-amusement pass, the game will save statistics to the e-amusement servers. As with other recent BEMANI games, e-amusement is also required for some unlocks and events.
