Rhythm Heaven Megamix

Rhythm Heaven Megamix (リズム天国ザ・ベスト+プラス), also known as Rhythm Paradise Megamix in Europe, and Rhythm World: The Best+Plus (리듬 세상 더 베스트+플러스) in Korea, is the 4th game in the Rhythm Heaven Series. It was released on June 11th, 2015 in Japan; June 16th, 2016 in the west during the E3 announcement; October 21st, 2016 in Europe; October 22nd, 2016 in Australia; and on December 1st, 2016 in South Korea.

This game includes 70 Rhythm Games from the previous three Rhythm Heaven games, 19 new ones, and 10 Remixes.

Main Game
In the single player mode of the game, the player helps a character named Tibby get back to Heaven World 天の国 (Ten no Kuni, a pun on 天国 tengoku) (mispelled as "Hevven World" by Tibby) by completing various rhythm games and restoring the flow. On his way, he meets various characters, such as Boondog, Dieter, Shep, Donna, Hairold, Eglantine, Trey, Bertram, Betty, & Phillip, who guide him through their various lands; as well as the Gatekeeper Trio, which consists of Saffron, Saltwater, and Paprika.

Challenge Land
Challenge Land is a new feature in Megamix. It becomes playable once the player clears the Lush Tower. It also allows up to 4 players, either through Local Multiplayer or Download Play. When clearing the course for the first time, Flow Balls are rewarded to players to spend it at Café. Those playing through Download Play cannot receive rewards, and are instead encouraged to purchase the full game.

Perfect Campaign
Perfect Campaign returns in Rhythm Heaven Megamix and up to 3 attempts are allowed before receiving the perfect. However, unlike from previous games in the series, some minor changes were made. Needing to navigate to the Rhythm Game where the Campaign is at is no longer necessary, as it can be accessed directly through the booth at Challenge Land. If the player missed during the attempt, the game ends with the message "You Missed..." instead of continuing like a normal game. After a "perfect" is obtained, the player no longer receives music or Reading Material; instead, each Perfect Campaign awards one Flow Ball, which can used to purchase Rhythm Items, Music, or Rhythm Games at the Shop.

List of Rhythm Games
The majority of games appear over the course of the story, where they are grouped into Stages of four; one from Rhythm Tengoku, one from Rhythm Heaven, one from Rhythm Heaven Fever, and one new. All towers have a Remix at the end as well.

The games in Honeybee Land, Machine Land, Citrus Land and Barbershop Land are shorter variants of the original games with new music and visuals. They take the original name and description of the games, while the actual original games are given new names, which in English often coincide with the Arrange games in previous installments.

Lush Tower
After the Lush Tower is cleared, the credits roll and Tibby attempts to return to Heaven World, only to crash back down. Some "powered-up" Rhythm Games also become available. The games in Honeybee Tower, Machine Tower, Citrus Tower and Barbershop Tower are actually the original games, but were renamed as the short variants in the respective lands take on the original name.

Songbird Tower
After the six towers of Lush Woods are cleared, the true credits roll and Tibby makes it back to Heaven World, but something is wrong when he arrives. Even more Rhythm Games get unlocked.

The Fourth Gate
The games at Mamarin Palace are like the Arrange games from previous titles. Karate Man Senior notably doesn't fit into this category.

From the Shop
Saffron's Shop allows the player to purchase Rhythm Items, Music and Rhythm Games. All games in the Shop are returning from previous games in the series. Some of them can be played on the Challenge Train even before they are bought.

Café
In the Café, the player can access (from left to right) StreetPass Terrace, Feed Goat, talk to the Barista and other characters, the Shop, Museum, Badges, Memories, and Mascots. The first two options are unlocked after clearing Lush Tower. The last three are available by talking to the Museum Curator.

Endless Games
Endless Games return in Megamix, which includes one game from each installment, and a new one of its own. They are unlocked by completing all three Trials set by the Gatekeeper Trio on that game's Gate, after which the endless version will be available in the Museum.

StreetPass Terrace
Whenever the player gets tagged by another player, the Cafe icon will display the Barista. For each player, the game displays their Mii, Flow, and Favorite Rhythm Game. Each player can be battled in Figure Fighter VS. This mode also has each character from the story to fight for those who can't use StreetPass.

Missing Games
While most games returned in Megamix, 24 didn't make the cut. The following are the games from past installments of Rhythm Heaven that did not return for Rhythm Heaven Megamix. (Arrange games whose normal variant is in RHythm Heaven Megamix are written in bold. Remixes, Endless Games, Games, and Two-Player Games aren't listed.) Many of these Arrange games have new patterns or new cues, which also exist in Rhythm Heaven Megamix, but are never used. It is debatable how many of these were actually intended to appear in the game or were simply leftover data from the porting process.

Scrapped New Games
In the debug menu of the game and through other sources, we can see even more games were intended to be included, but for one reason or another were scrapped.

For reference, the names internally use a system of categorizing games, using AGB, NTR, RVL and CTR for which installment they originate from, and S, L, A for Short, Long and Arrange games. For example, The Clappy Trio is AGBパチパチ三人衆S (agb_clap_S), The Clappy Trio 2 is AGBパチパチ三人衆L (agb_clap_L) and The Snappy Trio is AGBパチパチ三人衆A (agb_clap_A). A most curious case is Monster Tennis モンスターテニス (Monster Tennis). Unused text strings (which also curiously only exist in the Japanese version of the Rhythm Heaven Megamix Demo) show it would play differently to normal Rhythm Games, somehow requiring the player to use the Wii Remote, suggesting it was a scrapped project for the Wii (perhaps it was supposed to appear in Rhythm Heaven Fever) intended to be revived in this game. The player(s) have to use a tennis racket to fight monsters. Additionally, it would've featured four stages, several bosses and multiplayer. In the debug menu, Remixes and Gate games are after all the others. Four of these aren't available in the Japanese version's debug menu. Oddly, Quiz Show has three trials in this list but no Endless Game.

 * While using simple tap, it shows a character when tapping. This is a reference to Rhythm Heaven.
 * This the first game in the series to have threequels included.
 * It is notable that almost all of the title cards in most of the international versions of the game all use a small handful of font styles, and are rather simplistic compared to the more artistic and unique title cards in the Japanese version and Rhythm Heaven Fever.
 * This is noble in Rhythm Rally 1, 2, & Cosmic; Marching Orders; Catchy Tune 1 & 2; Super Samurai Slice 2; Built to Scale; Packing Pests; Micro-Row 1 & 2; Working Dough 1 & 2; Screwbot Factory; Monkey Watch; and various other minigames from Rhythm Heaven Fever.

 * This game has a few leftover/placeholder songs from Rhythm Heaven Fever.
 * The announcer in this game is voiced by Marianna DeFazio, who also voiced the announcer in Rhythm Heaven Fever.
 * After getting all of the Badges, a button with an alien-like creature on it appears. Tapping it will show you a picture of some of the staff.
 * This is the first game where no new Prologue jingles were made, aside from remixed ones from previous games and for Remixes.
 * This is the second game in the series, after Rhythm Tengoku, to have Karate Man as the first playable rhythm game.
