Sushi Striker wears its 3DS roots on its sleeve, but the core gameplay is addicting and the production values (minus the overworld) are top notch. Though it might appear like a high-end mobile game, this is the full-fledged real deal. If you don't mind dealing with a few pacing issues, this is easy to recommend to anyone who enjoys deep puzzle games.
There are some games that aren't meant to be taken seriously. Miitopia is one of those games. It's consistently fun, lighthearted and silly. Focused on character creation and interactivity instead of deep gameplay mechanics, Miitopia stands out as an easygoing alternative to the traditional RPG.
The Banner Saga is a marvel as a personalized adventure game. The experience of leading a caravan and constantly making impactful choices that directly decide their fates is one that I'll never forget (and one that I look forward to continuing in Banner Saga 2). However, though its SRPG elements are generally good fun, they're not quite as polished (or balanced) as the rest of the package.
Liar-soft has succeeded in crafting a cozy VN with a lovable cast of characters and heartwarming story that's well worth experiencing.
Iconoclasts is a game that you can't help but smile while playing. The meticulous attention to detail in every facet of the game save its storytelling (which is good, just not great) is remarkable. Failure to capitalize on the Switch's HD Rumble is a bit disappointing, but it's a minor blemish on an otherwise excellent experience.
If you're a hardcore Strategy-RPG fan and have a Switch, Disgaea 5 Complete is a godsend. The amount of content here is incredible and frankly a bit intimidating. The depth series veterans cut their teeth on is fully intact, and the game works perfectly as a portable experience. This is immediately one of the strongest titles for the Switch and sets the standard for what third party support for the system should look like going forward.
