You're being deliberately obtuse.
There is no game called "New Mario Bros Dream Team Bros.". Mario and Luigi RPG 4 is subtitled Dream Team Bros in Europe. That game is an
RPG.
New Super Luigi U is
downloadable content for New Super Mario Bros U.
Mario
Party is a Mario Party game.
Mario and Donkey Kong is a series of
puzzle games, the newest release of which is a top-down title with some sort of Pipe Dream-like mechanics.
Yoshi's Island is a series of games where you play as Yoshi. There are two unreleased Yoshi games right now: Yoshi's Island
3DS, and a Yoshi game for Wii U featuring a
yarn aesthetic.
