《超級機器人大戰COMPACT3》（スーパーロボット大戦COMPACT3）是WonderSwan平台上COMPACT系列的第五作，也是最終作。作為系列的收官之作，引入多部新作品，包括《合身戰隊メカンダーロボ》《魔境傳說アクロバンチ》《天空之艾斯卡弗洛內》《ベターマン》等少見且非主流的作品，使玩家對於參戰陣容感到耳目一新。此外，原先僅以隱藏元素形式登場的《New Story of Aura Battler DUNBINE》（聖戰士丹拜因OVA）首次正式參與故事情節，並呈現完整的原作再現。

遊戲的劇情中，COMPACT系列一貫的原創勢力「修羅」以《北斗之拳》為靈感來源，雖然其存在感和設定帶有模仿意味，但角色人氣不俗，甚至有角色以北斗七星命名。故事中原創主角修羅族戰士的弗爾卡·阿爾貝克(フォルカ·アルバーク)，他的能力極為強大，堪稱單機無雙，其搭乘的主機ヤルダバオト不僅在近距離擁有高威力必殺技，還能以低成本進行遠程攻擊，兼具リアル系運動性與超級系HP、防禦的優勢，序盤到終盤始終是自軍的王牌單位。中盤解鎖的強化型態ヤルダバオト·神化更獲得飛行能力與EN小幅回復，使其戰場持續力進一步提升，成為遊戲中最強的單位。

遊戲系統方面，廢除以往COMPACT系列的「個人資料表格系統」，改以戰鬥中獲得的PP在Intermission中培養駕駛員。為增加PP獲得效率，新增精神指令「修行」與「傳授」，前者自用，後者作用於任意同伴。整體遊戲並未設置宇宙地圖，僅限陸、海、空三種地形，這與《天空之艾斯卡弗洛內》的參戰設定相關。

在戰鬥表現與演出方面，本作的特色十分突出。無論是駕駛員還是機體，切入畫面（Cut-in）豐富且充滿動態效果，與同期《D》系列的靜態Cut-in形成差異。部分較小眾的角色與機體也得以呈現，例如《丹巴因》中的托卡馬克、澤拉娜、德羅等角色。GBA時期未實裝的動態機體特效，如《ベターマン》中角色的乳搖，首次出現在本作中。音樂方面，COMPACT系列一貫的高質量BGM在本作亦得以延續，版權作品選曲偏向核心粉絲，主題曲《約束はいらない》（《艾斯卡弗洛內》）、《夢之獵人》（《アクロバンチ》）、《鎮-requiem》（《ベターマン》）等均有收錄，原創BGM如主角フォルカ與對手フェルナンド的主題曲亦頗受好評。PCM音源下的角色叫聲使用廣泛，例如《マジンガーZ》的「ゼェェット！」與《メカンダーロボ》的「トライアターック！」均呈現高音質效果。

然而，遊戲亦存在平衡性與系統設計上的問題。原創主角因能力過高而破壞平衡，精神指令豐富且技能適合格鬥，導致單機即可通關。版權作品方面，《丹拜因》與《艾斯卡弗洛內》的世界設定被孤立呈現，異世界之間頻繁跳轉，導致情節分散；《メカンダーロボ》《ベターマン》《アクロバンチ》則因登場時間晚或劇情安排不足，存在原作再現不完全或空氣參戰的問題。此外，部分機體如《艾斯卡弗洛內》初期裝甲薄、回避率低，精神指令受限，使用體驗不佳；《メカンダーロボ》則因火力高但命中低而需依賴精神指令補助；《アクロバンチ》的登場較晚，無法充分發揮戰力。

系統設計方面，武器改造從單獨改造改為批量改造，但部分機體因運動性或特殊能力，格鬥系單位優於射擊系。PP培養系統雖然可提升駕駛員能力，但所需PP偏高且習得指令消耗過多，實際強化效果有限。隱藏單位數量稀少，且沒有二周目引繼系統，使周回玩法受限。

市場上，因發行量僅15,000本而極為稀少，二手市場價格高昂，成為收藏玩家的熱門珍品。儘管發售時期與《スーパーロボット大戦D》接近而略顯黯淡，但因新參戰作品多為少見且意外的組合而引發討論。其動畫化Cut-in、精緻BGM與原創勢力設計獲玩家肯定，使其成為COMPACT系列隱藏的佳作。雖然劇情與平衡性存在瑕疵，但對於系列愛好者而言，仍是一款值得體驗的作品。部分原創角色與機體後來亦參與《OGS》的追加劇情《OG2.5》與其完全版《OG外傳》，延續其影響力。

總結而言，《超級機器人大戰COMPACT3》是兼具少見參戰陣容、精緻演出與高質量音樂的作品。在平衡性和劇情上存在問題，但其BGM、Cut-in與原創角色的表現為玩家留下深刻印象。作為COMPACT系列的收官作，以及Banpresto最後WonderSwan平台遊戲，它的獨特性和稀有性，使其成為系列愛好者必玩的經典之一。

Super Robot Wars COMPACT 3 (スーパーロボット大戦COMPACT3) is the fifth and final installment of the COMPACT series on the WonderSwan platform. As the series’ concluding title, it introduced several new and relatively obscure works, including Gasshin Sentai Mekander Robo, Akubanch: The Legend of the Dark, The Vision of Escaflowne, and Betaman, offering players a fresh and unexpected lineup of participating series. Additionally, New Story of Aura Battler DUNBINE—which had previously only appeared as hidden elements—was fully integrated into the story, providing a more complete representation of the original work.

In terms of plot, the game continues the COMPACT series’ tradition of featuring original factions, with the “Shura” organization inspired by Fist of the North Star. While the homage is evident, the characters gained notable popularity, with some even named after the Big Dipper constellation. The original protagonist, Shura warrior Folka Alberk (フォルカ·アルバーク), is exceptionally powerful, essentially capable of soloing the game. His main unit, Yaldabaoth, combines close-range high-damage finishing attacks with cost-effective long-range strikes, blending real-type mobility with super-type HP and defense. From early stages to the finale, Yaldabaoth remains the army’s ace. Its upgraded form, Yaldabaoth “Divine” (神化), unlocked mid-game, gains flight and minor EN regeneration, further increasing battlefield endurance and solidifying its position as the strongest unit in the game.

The game system removed the traditional COMPACT series “Personal Data Table” and instead allowed pilots to be trained using PP earned in battles during Intermission. To boost PP acquisition, the new mental commands “Training” and “Instruction” were introduced; the former applies to oneself, while the latter benefits any ally. Unlike previous entries, the game does not include space maps and only features land, sea, and air terrains, likely influenced by the inclusion of The Vision of Escaflowne.

In combat and presentation, COMPACT 3 stands out. Both pilots and units have dynamic cut-ins, contrasting with the static cut-ins of the contemporaneous Super Robot Wars D. Even lesser-known characters and units, such as Tokamak, Zelana, and Dro from DUNBINE, are represented. Dynamic unit effects that were absent in the GBA era, like character animations in Betaman, appear for the first time. The series’ trademark high-quality BGM continues, with a focus on tracks appealing to core fans. Theme songs like “Yakusoku wa Iranai” (Escaflowne), “Yume no Hunter” (Akubanch), and “Chin-Requiem” (Betaman) are included, alongside original compositions such as Folka’s and rival Fernando’s themes. PCM-based character voice samples are widely used, featuring high-quality recordings of iconic shouts, e.g., “Zet!” in Mazinger Z and “Try Attack!” in Mekander Robo.

However, the game also has balance and system design issues. The original protagonist’s overwhelming power and abundant suitable combat commands make soloing the game trivial. For licensed works, DUNBINE and Escaflowne’s worlds are presented in isolation, with frequent inter-dimensional jumps leading to fragmented storytelling. Mekander Robo, Betaman, and Akubanch appear late or receive minimal narrative focus, resulting in incomplete representation of their source material. Some units, like Escaflowne, have low armor and evasion early on, while command limitations hinder usability. Mekander Robo’s high attack but low accuracy necessitates mental command support, and Akubanch arrives too late to contribute effectively.

System-wise, weapon upgrades shifted from individual to batch upgrades, but melee units remain favored over ranged units due to mobility and special abilities. Although PP training can enhance pilot abilities, the high PP cost and heavy SP consumption for commands limit actual improvements. Hidden units are few, and no second-playthrough carryover exists, restricting replay value.

On the market, the game is extremely rare, with only 15,000 copies produced, making it a coveted collector’s item with high resale prices. Although its release coincided with Super Robot Wars D, which overshadowed it, the unexpected and unconventional selection of participating series generated discussion. Its animated cut-ins, refined BGM, and original faction design have been praised, earning it a reputation as a hidden gem within the COMPACT series. Despite some flaws in story and balance, it remains a worthwhile experience for fans. Some original characters and units later appeared in the additional scenario OG2.5 and its full version OG Gaiden in the OGS series, extending their influence.

In summary, Super Robot Wars COMPACT 3 combines a unique lineup of rarely-seen series, detailed animated presentation, and high-quality music. While it suffers from balance and story issues, its BGM, dynamic cut-ins, and original characters leave a lasting impression. As the final COMPACT series entry and Banpresto’s last WonderSwan title, its uniqueness and rarity make it a must-play classic for series enthusiasts.
