Nintendo previously Tweeted asking fans to vote for the top five questions out of fifteen that they wanted answers to about The Legend of Zelda: Tri Force Heroes. Once voting was closed and the top five questions were selected, Nintendo released a series of Tweets explaining both where the title fits into the Zelda timeline, and also explaining the absence of Purple Link.
To expand further on the previous Tweets, Nintendo has posted a Q&A section on the Europe website which answers the questions more elaborately, along with answering the other three questions from the list.
“Where does The Legend of Zelda: Tri Force Heroes fall in the series’ timeline?
The game takes place several years after A Link Between Worlds and features the same hero. Certain events bring him to the kingdom of Hytopia, where he dresses as he does in order to hide his heroic origins. There’s no telling where the other hero candidates come from, but the player character you control is the true Hyrulian hero from A Link Between Worlds. If you aren’t familiar with what he was up to in A Link Between Worlds, I’d definitely recommend giving it a play.”
There’s also information on why the developers decided on three players and not four:
“Why can The Legend of Zelda: Tri Force Heroes be played with only three players and not four?
There are several reasons. First, our thought with this game was to let you stack characters into a totem to reach higher places. Having four people would make rearranging this totem difficult, and the two people in the middle wouldn’t have much to do a lot of the time. In terms of the camera, too, we’d have to zoom out from the environment the higher the stack gets, which would naturally make the player characters smaller.
Having a trio creates certain advantages as well. If you’re divided into groups of two and one, the sole player gets worried about being separated from the group, and the other two get worried about how they’ve lost their partner. As a result, they’ll start to naturally stick together and try to work as a trio. Also, when a group of people are deciding upon something, they generally rely on majority vote a lot of the time. With four people, this creates the chance of a 2-2 tie, making it hard to make snap judgments on what to do next. Having a trio work together is suited pretty well for puzzle-solving.”
