《SIMPLE 系列 for Nintendo Switch Vol.5：THE 壞人兄弟》（日文原名：SIMPLEシリーズ for Nintendo Switch Vol.5 THE ヤンキーブラザー）是由Mayaka與Logite聯手開發的動作遊戲，於2025年11月27日在Nintendo Switch平台上推出。繼承日本經典「SIMPLE系列」的精神，以誇張、無厘頭、痛快的格鬥娛樂為核心，並結合現代玩家喜愛的Roguelite成長機制與喜劇風格演出，讓玩家在拳拳到肉的喧嘩戰鬥中體驗到極具特色的「不良兄弟魂」。

主題圍繞在兩位不良兄弟的喧嘩之旅，將操作他們在各種街頭戰場中不斷挑戰、強化與進化，最終目標是成為最強的Yankee。整體畫風結合昭和風格的熱血漫畫感與現代的卡通渲染效果，動作爽快、打擊感十足。開發團隊強調「簡單操作、無限爽感」，讓任何人都能在短時間內體驗到純粹的街頭格鬥快感。

系統方面，《THE 壞人兄弟》擁有極為獨特的三大強化系統。
第一是「喧嘩麻將系統」，每次出發戰鬥前會獲得一組“漢牌”，決定初始能力，而每次戰鬥結束後可使用戰鬥中收集的“證”進行“麻將對局”，藉由抽牌強化角色。這種結合運氣與策略的設計，讓成長過程充滿隨機性與刺激感。第二是「夥伴拉霸系統」，在戰鬥中若轉動拉霸成功湊出圖案，夥伴會現身支援，包括體力回復、發射光束、施放必殺技等。若觸發大獎「Jackpot」，則會解鎖第三系統「二名獲得系統」。「二名系統」是本作另一大亮點，可為角色取得各式綽號，從滑稽搞笑到酷炫霸氣，每個綽號都會帶來能力倍增的強化效果。獲得後可在下次挑戰時作為初始裝備使用，形成越戰越強的循環樂趣。

本作支援1至2人遊玩，雙人模式中第二位玩家可扮演兄弟支援角色進行「應援玩法」，無論在TV、桌上或掌機模式都可輕鬆享受。延續SIMPLE系列「親民價位、簡單上手、創意滿點」的傳統，卻加入前所未有的深度與誇張風格，被視為該系列十年來最具代表性的新作。

在市場評價方面，一經公開便在日本遊戲社群引起熱烈討論。玩家與評論者普遍認為它「讓人想起SIMPLE系列的黃金時代」，不僅回歸早期那種荒唐又熱血的搞笑氣質，還融合近年流行的Roguelite設計與現代美術風格，達到「懷舊與革新」的平衡。部分遊戲媒體更直言，本作是「SIMPLE系列的真正復活」，是對粉絲最誠意的致敬之作。此外，其宣傳美術設計也獲得極高評價。從角色造型到封面構圖都充滿昭和硬派氣息與現代色彩感，令人一眼就感受到那股「燃燒的男人魂」。遊戲定價仍維持系列親民傳統，吸引許多老粉與新玩家預購支持。

總體來說，《SIMPLE 系列 Vol.5：THE 壞人兄弟》不僅是懷舊玩家期待已久的街頭格鬥復活作，更象徵SIMPLE品牌重拾創意與狂氣的象徵。以誇張的劇情、幽默的對白、與極度爽快的戰鬥節奏，成功喚醒日本遊戲界久違的熱血魂，被視為2025年Switch平台上最具個性、最能代表「日本B級遊戲精神」的年度話題作之一。

SIMPLE Series for Nintendo Switch Vol.5: THE Yankee Brother (Japanese title: SIMPLEシリーズ for Nintendo Switch Vol.5 THE ヤンキーブラザー) is an upcoming street brawler action game jointly developed by Mayaka and Logite, set to release on November 27, 2025 for the Nintendo Switch. This title continues the legacy of Japan’s long-running “SIMPLE Series”, known for its affordable price and eccentric creativity, blending over-the-top humor, fast-paced combat, and a distinctly Japanese delinquent (yankee) spirit into a fresh, chaotic experience.

The story follows two hot-blooded brothers on their journey through endless fights to become the strongest “Yankees.” The game’s art style fuses Showa-era manga aesthetics with modern cartoon visuals, resulting in exaggerated, dynamic street battles full of comedic flair. The developers emphasize “simple controls, maximum fun,” ensuring players of any skill level can instantly enjoy the intense, combo-heavy gameplay.

At the heart of THE Yankee Brother are its three unique enhancement systems, which define the game’s roguelite progression.
The first, the “Brawl Mahjong System,” determines your initial stats through a set of “manly tiles” drawn before each fight. After every battle, players can use tokens earned in combat to play a mini-game and draw new tiles, introducing both strategy and luck into character growth.
The second, the “Partner Slot System,” allows players to trigger support actions by lining up slot icons during combat. When successful, your brother rushes in to heal HP, fire eye beams, or unleash special attacks. If players hit the jackpot, they activate the third system — the “Nickname Acquisition System.”
This third system grants players comical or badass nicknames, each providing major stat boosts or new passive abilities. Once unlocked, nicknames can be saved and equipped for future runs, creating a rewarding cycle of progression and replayability.

The game supports 1–2 players, with a co-op “Brother Assist Mode” allowing a second player to jump in as a backup fighter. It’s compatible with TV, tabletop, and handheld modes, offering flexibility and accessibility — core values of the SIMPLE Series. Despite its approachable design, the game boasts surprisingly deep combat mechanics and a strong sense of chaotic energy rarely seen in modern titles.

Market reception to THE Yankee Brother has been extremely positive since its announcement. Japanese gaming communities have praised it as a “return to the true spirit of the SIMPLE Series,” capturing the wild, comedic energy of early 2000s B-tier classics while introducing modern roguelite mechanics and stylish visuals. Reviewers noted that the game feels both nostalgic and fresh, combining the absurdity of old-school yankee brawlers with today’s fast, responsive gameplay. Some critics have even called it “the true revival of the SIMPLE brand,” applauding its balance of parody, punch, and personality.

The game’s package art has also been celebrated — a perfect homage to the macho, over-the-top design style of vintage Japanese beat ’em ups. Fans describe it as “pure 2000-point energy,” overflowing with charm and attitude. Priced affordably as with all entries in the SIMPLE Series, the title has quickly gained traction among both loyal fans and new players.

In summary, SIMPLE Series Vol.5: THE Yankee Brother is more than just a humorous fighting game — it’s a nostalgic yet innovative revival of Japan’s quirky budget-game culture. With its bold visual style, explosive combat, and tongue-in-cheek storytelling, it stands out as one of the most distinctive and anticipated Nintendo Switch releases of 2025, perfectly embodying the chaotic, passionate, and proudly “B-grade” soul that made the SIMPLE Series iconic.
