Design an Extra Stage System

beatmaniaIIDX Renaissance
Based off of the planes/chain of being that came about during the Elizabethan era. History~ The Renaissance and the Elizabethan era are technically different, but the Elizabethan era was during the Renaissance so I'm counting it.
Each plane consists of four songs for certain parts of that plane: two KOs, a crossover, and a revival. Each plane also has a boss.
Haven't thought of a good system for unlocks yet

ultimate bump lol

Anyway, I got an idea of an extra stage system.

WORLD EVOLVED
How to unlock the folder: You have to clear a minimum total difficulty of 30 with an A or above to unlock this extra stage.

Mechanism: You have to fill the EVOLVING GAUGE of each region. You first pick what region you want to be EVOLVED, then you will enter a specific area which is a square that is divided by four. The theory is the larger part of the area you are about to claim, the harder the boss becomes. Enter a part and play the boss song. The more achievement you get, the more longer the time the area is undisturbed. This is the list of the achievement:
Playing on NORMAL: +1 h
Playing on HYPER: +2 h
Playing on ANOTHER: +3 h
HARD GAUGE ON: +0,5 h
EX-HARD GAUGE ON: +1 h
Clearing with A: +1 h
Clearing with AA: +3 h
Clearing with AAA: +5 h
BORDER BONUS: +2 h
Full Combo: +3 h
All Perfect Great: +5 h
Perfect Score (200,000): +10 h
Successfully claiming an area will full the EVOLVING GAUGE. Over time, when the time the area undisturbed is over, the EVOLVING GAUGE bar will decrease and the area will have to be reclaimed. This is when a new song will appear. Clear the song to get achievements and got your achievement hour multiplied by 1.5.
There are 5 regions to be available, and fulling the EVOLVING GAUGES will unlock the EES.

World Tower has been brought up to 100 songs. I think it's finished now.

EDIT: I lied.

Added 17 new songs to World Tower, added ratings to all 117, switched the game to jubeat, and fleshed out the mechanics a bit more.

Very interesting. Are those all Extra Stage songs though? Theres more boss songs than there are regular songs in a typical IIDX game.

It's more of turned into a general songlist accessed via Extra Stage.

beatmaniaIIDX EXODUS REVOLUTION
This game would essentially be a IIDX version of DDR X3 vs. 2ndMIX, but with some differences. First off there would be two main game modes: CLASSIC MODE and DX MODE. The main generic song list would be the same in both modes except for the play style; CLASSIC MODE is 5KEY play only while DX MODE is 7KEY play only. These two modes are also the keys to accessing the EXTRA STAGE systems.

EXTRA STAGE system 1: BEATS LOST AND FOUND COLLECTION
Description: Overall this system works similarly to Lincle Kingdom, but with some differences. Both modes feature special accessible areas that sport exclusive songs for each area. Each exclusive song is a revival that were once "lost" and now you have to "find" them. Since this is a long, drawn out process, you simply have to CLEAR each song to "collect" them (which is necessary for a later event). Each revival also feature brand new charts.

EXTRA STAGE system 2: EXTRA PARALLEL ROTATION
Description: After collecting all of the revivals from each area in each mode, a third mode is revealed MEGAMIX MODE, which is simply a full collaboration of every song you "collected" along with the regular song list, and let's you specifically choose what songs you want to play in 5KEY or 7KEY style, among other modifiers. Playing in this mode allows you to access the second EXTRA STAGE system called EXTRA PARALLEL ROTATION. To access it, simply meet the traditional requirements for an EXTRA STAGE. Once you do, you will have access to these nine songs:

SEEING RED / Killer Returnss
Dreams of a HAPPY SKY / CALF
DistorteD SoundwaveS / wac
PARTY IN GOLD STYLE / good-cool
ATTENTION! DJ TROOPERS! / L.E.D.-G
Reign of the EMPRESS / jun
Starlight SIRIUS / Mystic Moon
Resort Anthem Celebration / DJ Mass MAD Izm*
LINk-Connection-circLE / dj TAKA

EXTRA STAGE system 3: ONE FINAL EXTRA STAGE
After all of the EXTRA PARALLEL ROTATION songs are cleared, yet another mode is revealed for play, but this is different. The mode is simply called GRAND FINALE and only has one song. This song is about the length of what you would spend playing a regular game in STANDARD MODE in other IIDX installments as part of it is a megamix of existing songs from beatmania 1stMIX all the way to beatmaniaIIDX19 Lincle (not EVERY single song, though). As such, this would be the absolute final song of beatmania and the close of the series:

The EXODUS of beatmania / DJ Mass MAD Izm* and beatmania all stars

BUMP due to inspiration

beatmaniaIIDX21 Astral Aura
ALLITERATION ASTROLOGY EXTRA STAGE System

CARDINAL PHASE
[AGGRESSIVE ALTERNATIVE] ACTION AUGMENTED / Aries (96)

[PASSIONATE POP] Purpose perceptive / Pisces (Ryu*)

ONE MORE EXTRA STAGE
[ORNATE ORCHESTRAL] opaque origin / Ophiuchus (Zektbach)

I can't think of requirements to access the system and songs, though.

I was thinking of an extra system for DDR and realized that the result could work in IIDX as well. Unfortunately I could only think of unlock requirements for one segment of it.

FRAGMENTED DUALITY
Similar to Legend Cross but instead of two requirements to unlock one song, one requirement unlocks two songs that are played back-to-back as Extra Stage and OMES.

Time and Space:
For all three rounds, the songs must have different BPMs, of which one must have BPM changes AND they must be all in different group folders. The final song must be Hard or EX-Hard Cleared.
CONTINUUM SHARD
ES: Space: [DRUMSTEP] Wormhole / Nhato vs. Eagle
OMES: Time: [ERRATIC HARDCORE] Broken Loop / Sota Fujimori ∞

Light and Dark:
SPECTRUM SHARD
ES: Light: [VARIABLE TRANCE] PRiSMATIC / Ryu* with Another Infinity
OMES: Dark: [FREEFORM HARDSTYLE] SHADOWS EMBRACE / L.E.D.-G

Air and Sea:
PRESSURE SHARD
ES: Air: [SPEED BREAKS] Macrostorm / CAPACITY GATE
OMES: Sea: [DEEP TRANCE] Cold Abyss / DJ YOSHITAKA x Tatsh

Life and Death:
??? SHARD
ES: Death: [DOWNTEMPO] nonexist / 猫叉Master
OMES: Life: [HAPPY HARDCORE] Creation Union / Risk Junk

After all four Shards are unlocked, EX-Hard AAA'ing one of the Extra Stages unlocks the true OMES.

WORLD SHARD
[ELECTRONIC PROGRESSION] All Connect / DJ MDRT (Mass MAD Izm*, Dirty Androids, Remo-con, TECHNORCH)

I want that to be real.
