Mario & Sonic at the Rio 2016 Olympic Games (Wii U)

Mario & Sonic at the Rio 2016 Olympic Games is a sports title for the Wii U, which is the fifth installment on the Mario & Sonic series, along with the Nintendo 3DS version. Like the other games, it takes place in the host city of the Olympics of the corresponding year, being Rio de Janeiro.

Copacabana Beach
In the game, the main menu, called Shortcut Menu, is unlocked after winning a medal in the first tournament, is optional and is activated with the button. The game always starts instead on Copacabana Beach, that is explorable and contains several characters the player can talk to, either characters from Team Sonic and Team Mario or Miis of other players. Furthermore, when the player is participating in a tournament, all the characters participating in said tournament can be found at the beach. By talking to Miis of players from unknown countries or by talking the first time to characters from Team Sonic or Team Mario after entering the first tournament, countries' and characters' flags can be obtained respectively. While participating in a tournament, there are also Miis that give suggestions about hidden controls of features of the tournament's event, some but not all of them are in the form of a card that can be collected and is shown after each match in said event. Furthermore, after participating at least once in the Heroes Showdown mode, there are Miis that can give suggestion cards about the Heroes Showdown mode. When characters from Team Mario or Team Sonic are found at the beach, one Mii also gives additional information about one character, chosen randomly among at least two small pieces of information of this kind per character. In addition to this, there are important locations and characters that can be talked to in order to access the game's modes, to purchase items or to obtain additional rewards, these are:

The carnival challenge consists in winning in an event against the character while satisfying peculiar conditions. In order to participate in said challenge, the player must pay either Rings (for Sonic's and Dr. Eggman's floats) or Coins (for Mario's and Bowser's floats).

Tournaments
Tornaments, unlocked after winning in five single events, are event-specific and consist in three phases (qualifications, semifinals, finals), in each of which half of the athletes are eliminated. If the player manages to end up in 1st, 2nd or 3rd place, a gold, silver or bronze medal is earned. Furthermore, a special prize is earned if a condition related to each tournament is satisfied. Four levels of increasing difficulty exist. Characters from Team Sonic and Team Mario can sometime participate in tournaments of level 2 or higher. In each torunament, difficult to beat athletes are indicated with an exclamation mark. Finally, guests of the particular event of the tournament may appear after the qualification is passed, if the player talks to them their flag is earned, furthermore if the tournament is succesfully cleared, the guest challenges the player and, if beaten, is unlocked.

Leagues
Leagues are special tournaments that can be accessed after winning 25 tournaments using either an amiibo related to the Mario universe or a Sonic amiibo. The Mario League, accessed with a Mario-related amiibo, has the player's Mii facing opponents from Team Mario, while the Sonic League, accessed with the Sonic amiibo, has the player's Mii facing characters from Team Sonic. The reward of the Leagues is either a Mario or a Sonic Mii costume.

Heroes Showdown
A Heroes Showdown mode is featured as well. It is unlocked after getting the gold medal in all the single events or after getting more than seven bronze medals in the tournaments. In it the player joins either Team Mario or Team Sonic and participates in knockout rounds against members of the other team in events chosen randomly, until either all members of one team or one of the two captains; Mario and Sonic, are knocked out.

amiibo
The game supports amiibo functionality, accessed from the Shortcut Menu after winning a medal in 25 tournaments rather than by talking to a character in Copacabana Beach. A Mario-related amiibo lets the player enter the Mario League, the Sonic amiibo lets the player enter the Sonic League, while all other amiibo will give either coins or rings.

Costumes
As with the previous games, there are a variety of collectable costumes for the player to use for their Mii character. A majority of the costumes return from the previous installments, in addition to some brand new ones.

Music
As in the previous installments, music can be collected. All guests' themes are unlocked after beating them in an event.

Stamps
Players are able to obtain stamps to use in Miiverse posts. There are a total of 100 stamps in the game. Stamps are obtained at the item stands.

Pre-release and unused content
The game originally featured Boom Boom among the playable characters of Team Mario in the introductory video of the game shown in the Nintendo Direct of March 2016. This video was also reused as the introduction of the game. Despite this, in the final game Dry Bowser, who doesn't appear in the introduction among the playable characters of Team Mario and is only referred to through his flags, replaces Boom Boom and the only playable Boom Booms are the supporting characters of the Rugby Sevens events. Additionally, Birdo is shown as a goalie in the Duel Football event. In the final game, Birdo is replaced by different colored Birdos as goalies while Birdo makes no appearance in the game aside from appearing at the Heroes Showdown sand statue.

Trivia

 * This is the first home console Mario & Sonic game to be released on the same year of the Olympics in real life, being released six weeks before the Opening Ceremonies.
 * This is the first home console Mario & Sonic game where all of the events take place in real life locations.
 * Like in Mario & Sonic at the Sochi 2014 Olympic Winter Games, there are special animations for some paired characters for whenever the player gets first place in a team event, all being recycled from that game (with some new ones added for characters like Mario and Toad, Sonic and Jet, Rouge and Blaze, and Donkey Kong and Diddy Kong).
 * One of the additional pieces of information told by Miis about Wendy O. Koopa references her battle in New Super Mario Bros. U, where she uses ice skates and her battle stage is made of ice, further suggesting she will be a playable character in at least an ice skating event of a future Mario & Sonic game dedicated to the Olympic Winter Games.
