It's Splatoon. I'm not that big of a fan of the esthetics or the world but Splatoon's gameplay to me is quintessential Nintendo and what I love in videogames. It's both extremely easy to grasp and simplistic on a surface level but with an insane level of depth once you start really getting into it. It manages to cram countless actions that are their own separate mechanics in other shooters (reloading, healing, running, wall climbing, stealth, area control, damaging and debuffing enemies, XP gain) into a single loop: shooting ink, turning a squid, which gives the game a unique feeling of coherence. The feedback is phenomenal which means that simple basic movement is satisfying in itself and the core mechanics are so versatile they can be used for a ton of different gameplay styles and scenarios. Finally the implementation of gyro aiming adds another layer of skill and a fluidity (no pun intended) to the controls that elevate Splatoon over every other game in terms of pure interactivity.
