The Legend of Heroes: Trails of Cold Steel IV is massive. It's massively fun and massively rewarding. Fans of JRPGs can get delightfully lost in its deep story, its numerous characters, and its battle system that provides a ridiculous amount of options for customization. Just make sure you've played Trails of Cold Steel III (and have at least read up on I and II).
With its unique visuals, clever environmental puzzles, and non-violent gameplay, El Hijo is a welcome entry in the somewhat overlooked stealth/puzzle genre. If you don't buy into the gameplay before the repetition sets in, however, it can become an adventure that's easily abandoned.
Although the improv gameplay of What the Dub?! is somewhat basic and repetitive, it presents numerous opportunities for MST3K-style hilarity. You don't need to be a fan of movies to enjoy this party game; you just need to be quick-witted (or have funny friends).
With its medieval setting and alchemy-based combat system, Black Legend looks and plays quite a bit differently from most turn-based strategy games available on the Switch. Its repetitive settings and battles, however, will likely turn away those used to a greater degree of variety and fun.
Castle Kong gives Donkey Kong a colorful visual refresh and an extreme challenge bump, but otherwise sticks closely to the formula that made it a legend. Fans of classic arcade games will enjoy it, and will be thankful they don't have to drop another quarter with each frustrated restart.
Although it occasionally gets bogged down under its own ambition, Atelier Ryza 2: Lost Legends and the Secret Fairy is consistently surprising and fun. It may lack the melodrama and heroics of most JRPGs, but it still offers a lengthy campaign full of compelling combat and exploration.
