A premium-quality six-panel infographic illustration explaining the historical development of a landmark 1981 arcade game in a colorful educational comic style. The artwork combines polished American comic-book energy with classic Japanese manga storytelling. Each panel has bold title banners, cinematic composition, vibrant colors, expressive characters, and clean educational layouts. The infographic intentionally avoids all copyrighted characters, logos, game graphics, level layouts, and recognizable visual designs. Every character, sprite, and game element is completely original while conveying the technological atmosphere of early 1980s arcade development. Panel 1 — 「切迫」 A warehouse filled with stacks of wooden shipping crates labeled in Japanese: 「シューティングゲーム」 「2000ユニット 売れ残り！」 The warehouse belongs to a fictional North American arcade distributor. A wall calendar shows several months passing while a cargo ship icon symbolizes a four-month shipping delay. Workers look worried. Large title: 「切迫」 -------------------------------- Panel 2 — 「発想」 A young Japanese game designer sits at a desk thinking deeply. Behind him is a whiteboard covered with sketches. Instead of copyrighted characters, the board contains completely original concepts: ・「ゴリラ」 ・「大工」 ・「レディ」 Each design is extremely simple and generic. Another section of the whiteboard shows arrows connecting 「ジャンプ」 「梯子」 with rough gameplay concepts. Small pixel mockups appear only as primitive square blocks with no resemblance whatsoever to any existing video game character. Large title: 「発想」 -------------------------------- Panel 3 — 「急造」 Inside a busy Japanese development office. Engineers work frantically around vintage early-1980s computers. Documents cover every desk. A wall sign reads 「池上通信機」 A large calendar points toward July. Big handwritten note: 「締切まであと2ヶ月半！」 Everyone looks exhausted but determined. Large title: 「急造」 -------------------------------- Panel 4 — 「流用」 Close-up of hands replacing one arcade circuit board with another inside an arcade cabinet. The removed board is labeled 「旧ゲーム基板」 The new board is labeled 「新作ゲーム基板」 A speech balloon: 「帳尻合わせ！」 On the floor lies a contract stamped 「和解成立　1990」 Large title: 「流用」 -------------------------------- Panel 5 — 「発売」 A lively Japanese arcade in the summer of 1981. Students and young adults crowd around upright arcade cabinets. The CRT monitors display only simple attract-mode text. No gameplay. No characters. No recognizable layouts. One screen simply displays "Climb! Jump!" in a crude early-1980s bitmap font. Visible CRT scanlines. Curved CRT glass. Phosphor glow. Players cheer. One excited player raises both hands. Another points at the score. A score display simply reads 120000 No game graphics appear anywhere. Large title: 「発売」 -------------------------------- Panel 6 — 「転換点」 A dramatic symbolic ending. A sunrise behind a city skyline. Floating above are three anonymous primitive pixel-art sprites: A gorilla. A construction worker. A lady. All three are completely original. Their sprites must imitate authentic **1981 arcade hardware limitations**: • approximately 16×16 to 20×20 pixels • only 4–6 flat colors • no anti-aliasing • no gradients • no smooth edges • large square pixels • extremely primitive • abstract silhouettes • early-1981 arcade hardware limitations • NOT modern pixel art • NOT HD pixel art • NOT indie-game pixel art • NOT resembling Donkey Kong, Mario, Pauline, Jumpman or any existing arcade character. The sprites should feel like an imaginary arcade game from 1981 that never actually existed. Large Japanese text: 「創造的リスクへの挑戦！」 Below it: 「ここから任天堂の快進撃が始まった。」 -------------------------------- Overall style Highly detailed educational infographic. Bright colors. Museum-quality historical illustration. Comic-book composition. Japanese text only for captions. No copyrighted game graphics. No recognizable sprites. No Nintendo logos. No Donkey Kong. No Mario. No existing game UI. Everything must remain historically inspired while completely original.
