《魔界戰記4 Return》（日文名：魔界戦記ディスガイア4 Return，英文版名：Disgaea 4 Complete+）是日本知名戰略角色扮演遊戲系列《魔界戰記》（Disgaea）的第四部本傳作品強化版，由日本一Software（Nippon Ichi Software）開發。原作於2011年首次登場於PlayStation 3平台，而Switch上的「Complete+」版本則是以PlayStation Vita版《Disgaea 4 Return》為基礎，加入更完善的UI、調整遊戲節奏、整合所有DLC內容，於2019年在Switch平台上登場。提供更加便利與完整的遊玩體驗，是目前最推薦的入門平台之一。

劇情方面，主角是名為瓦爾巴托賽（Valvatorez）的吸血鬼，曾是魔界中令人聞風喪膽的暴君，但由於立下「永不吸人血」的誓言而失去力量，轉而成為「地獄」中負責教育新死者的低階官員——普利尼教官。劇情的開端，是瓦爾巴托賽對腐敗體制的不滿，以及因上層決策讓普利尼（遊戲中經典企鵝模樣的亡者）被大量消滅，而決定與忠誠的狼人隨從芬里克（Fenrich）一起推翻整個魔界政府，踏上革命之路。

雖然設定在地獄與魔界，故事卻充滿誇張幽默、反諷政治與道德問題的橋段，例如「為了守護誓言而不吸血的吸血鬼」「政治腐敗下的體制鬥爭」「不死生物追求正義」等等，使其在輕鬆搞笑之中仍帶有一點哲思。角色眾多，每位都有鮮明個性，從忠誠如狗的芬里克、痴迷正義的天使、到政治萬能的總統候選人等，構成一個荒誕而可愛的魔界革命團體。劇情雖然誇張，但在後期帶入一些關於承諾、信念與犧牲的沉重主題，使整體故事層次豐富而引人入勝。

在操作與系統上，延續系列一貫的深度策略玩法。採用方格戰棋形式進行，每位角色可依照其移動力、攻擊範圍、技能來規劃戰術，搭配地形屬性「Geo Panel」與「Geo Block」產生連鎖反應，使得戰場策略充滿變化。角色之間還有「投擲系統」、「合體攻擊」、「塔式疊人」等系列經典機制，讓每場戰鬥都可玩性十足。

最著名的特色，是幾乎無上限的角色培養系統。等級上限達9999，傷害值可突破千萬，搭配「轉生」系統可以無限洗鍊角色屬性，打造夢幻戰力小隊。此外，引入「魔界議會」系統，能投票修改遊戲內規則，例如增加經驗倍率、開放特殊商店等等，也能透過「懲罰房間」教訓不配合的議員，使遊戲過程極具自由與趣味。

Switch的Complete+版還整合大量原本需另購的DLC，包括額外劇情章節、新角色、新職業與特別模式等。圖像部分則維持原作的2D精緻人物立繪與Q版戰鬥模組，風格一如以往的鮮明可愛，但也因年代關係畫面表現上較現代作品略顯簡單。不過整體在Switch上運行順暢，支援便攜與TV模式交替遊玩，體驗便利。

市場評價方面，獲得中上程度的肯定。Metacritic分數在85分左右，普遍認為這是Disgaea系列中劇情最成熟、角色塑造最成功的一作，戰鬥系統也在維持系列複雜深度的前提下更加人性化，對新手而言相對友善。有玩家讚賞它以諷刺方式描繪魔界政治與官僚主義，劇情爆笑又不失溫情，讓人意外地感動。但也有評論指出，其育成系統仍舊偏向硬核，若要真正體驗後期挑戰內容，仍需大量重複練等與刷素材，對時間有限的玩家來說可能顯得冗長。而畫面未有明顯進化，對於追求視覺震撼的玩家可能較無吸引力。

總結來說，《魔界戰記4 Return / Disgaea 4 Complete+》是兼具深度與搞笑、戰略與情感的SRPG佳作，既保有系列粉絲熟悉的高自由度與極限練功，又透過有趣角色與政治諷刺劇情吸引新玩家加入。對喜愛日式策略遊戲或角色養成模擬的玩家來說，是Switch平台上不可忽視的代表作。

Disgaea 4 Complete+ (Japanese title: 魔界戦記ディスガイア4 Return) is an enhanced version of the fourth main installment in the acclaimed Japanese strategy RPG series Disgaea, developed by Nippon Ichi Software. The original game debuted on the PlayStation 3 in 2011, while the "Complete+" version for the Nintendo Switch, released in 2019, is based on the PlayStation Vita edition (Disgaea 4 Return). This version features refined UI, better game pacing, and includes all DLC content, making it one of the most recommended entry points for newcomers to the series.

The story centers on a vampire named Valvatorez, a once-feared tyrant of the Netherworld who has lost his power due to an oath he made never to drink human blood again. As a result, he now serves as a low-ranking official in the underworld—specifically, a Prinny Instructor, tasked with training newly deceased souls transformed into penguin-like beings called Prinnies. The plot kicks off when Valvatorez grows discontented with the corrupt Netherworld bureaucracy and sets out to lead a revolution after higher authorities begin mass-destroying Prinnies. He is joined by his loyal werewolf servant Fenrich as they rise up to overthrow the demonic regime.

Although set in the hellish Netherworld, the game delivers its story with a heavy dose of humor, over-the-top antics, and satirical takes on politics and morality. Themes like “a vampire who refuses to drink blood for the sake of honor,” “bureaucratic absurdities,” and “undead creatures pursuing justice” all contribute to a comedic yet occasionally thought-provoking narrative. The game’s large cast of quirky characters includes loyal lieutenants, justice-obsessed angels, and even demon politicians vying for office, forming a bizarre and endearing band of revolutionaries. While the tone is generally light-hearted, the story grows deeper toward the end, touching on themes of loyalty, sacrifice, and belief in ideals.

In terms of gameplay, Disgaea 4 Complete+ maintains the series' signature depth and complexity in tactical combat. Battles take place on grid-based maps, with players issuing turn-based commands to characters. Strategic elements are enhanced by environmental effects like Geo Panels and Geo Blocks, which introduce puzzle-like conditions and chain reactions. Core mechanics such as character throwing, team attacks, and tower stacking are present, offering layered strategies for each encounter.

One of the game’s most distinctive features is its virtually limitless character development system. Characters can level up to 9999, deal damage in the millions, and be "reincarnated" to refine their stats repeatedly. The game also features the Dark Assembly (translated as “Netherworld Assembly”), where players can pass in-game legislation—like unlocking new classes or boosting experience gains—through voting, bribery, or even punishing uncooperative senators in the "Discipline Room." This gives the game a playful level of meta-strategy and customization rarely seen in other SRPGs.

The Switch’s Complete+ edition includes all previously paid DLC, such as bonus scenarios, extra characters, new classes, and challenge modes. Visually, it retains the classic 2D sprite artwork and chibi-style battle models the series is known for. Though it may look dated compared to modern games, the presentation is vibrant and charming. Performance on the Switch is stable, and the flexibility of handheld and TV modes makes for a smooth and accessible playing experience.

Critically, the game has received generally favorable reviews, with a Metacritic score hovering around 85. Fans and critics alike have praised its well-crafted story, complex yet rewarding combat system, and memorable characters. It’s often regarded as one of the most refined entries in the series, particularly in how it balances depth with accessibility. Players have also lauded the game’s satirical take on political corruption and bureaucracy, saying the plot, while ridiculous, is surprisingly heartfelt and engaging.

However, not all feedback is positive. The character-building system, while powerful, can feel overwhelming or grind-heavy for some players—especially those with limited time. To fully access late-game content, significant repetition and resource farming are required. Also, the visuals, while faithful to the original, may appear simplistic to those seeking cutting-edge graphics.

In conclusion, Disgaea 4 Complete+ is a standout SRPG that fuses depth, humor, strategy, and emotion in a uniquely Japanese style. It remains a favorite among series veterans while offering an approachable yet rich experience for newcomers. For fans of turn-based tactics, character development, or offbeat storytelling, it stands as one of the must-play strategy games available on the Nintendo Switch.
