Mario & Luigi: A Tale of Three Relatives

Mario & Luigi: A Tale of Four Siblings (also known in Japan as Mario & Luigi: Frost and Leaflet) is a role-playing game developed by SpectraGear Games and published by Nintendo on the Nintendo Switch around Spring 2021 after AlphaDream's bankruptcy. 
== Story ==
Mario and Luigi have been invited with Peach to Fariden Island to celebrate the kingdom's Marvelous Festival and the birthday of Prince S. Jasper, with Starlow and her toad assistants to assist them. Arriving at the capital's port, the group comes just in time for the festival's opening, and then split up afterwards to explore.
After a while of exploring however, two figures catch the brothers' and Starlow's attention, one of which resembles Mario and Luigi. When talking to them, it's revealed that they are known as Diego S. and Isa, two of the brothers' relatives that have lived on the island with their family since childhood.
== Gameplay ==
A Tale of Four Siblings, like many Mario & Luigi titles, has the player take control of both Mario & Luigi as they explore a vast world fighting enemies. This time, they explore the Fariden Island in search of the Rosel Stars with the additional help of Diego and Isa.
=== Battle System ===
The basic method of starting battles is having one of the brothers touch, jump, or hit an enemy first. Jumping on them or hitting them with a hammer would deal additional damage or stun them before the battle starts. This is also the case for the brothers as well. Like many turn-based battles, Mario and Luigi will have to switch turns with the enemy.
