Ueda said ICO's hand-holding grew out of thinking about Another World's alien relationship. Both men described influence as indirect: what they absorb over a life seeps into the work rather than being quoted.","whyItMatters":"The session documents two designers agreeing on a working premise rarely stated out loud: a game world can exist for its own sake rather than as a frame for rules and scores, which is what Ueda says Another World taught him.","webCardHtml":"\u003cp\u003eThe event ran two days at the Institut francais du Japon in Tokyo, on September 22 and 23, 2026. The second day put Chahi and Ueda on one stage, and the conversation started on influence rather than craft.\u003c/p\u003e\u003cp\u003eUeda first played Another World on the Super Famicom at a friend\u0026#39;s house while he was a university student. What stayed with him was not a mechanic. It was the sense that a world sat inside the screen, without the point counts and rules that other games of the period let show through, which led him to the formulation that you can build a world for the world\u0026#39;s sake, not for the game\u0026#39;s sake. Chahi traced a return influence the other way, saying the shadow enemies in Ueda\u0026#39;s work reminded him of Heart of Darkness.\u003c/p\u003e","blueskyPost":"Ueda traced ICO's hand-holding to Another World's alien relationship.

The useful part is the direction: influence here runs sideways between two working designers, not downward from a canon neither of them cites directly.","newsletterBlurb":"At The Tenth Mosaic in Tokyo, Eric Chahi and Fumito Ueda sat down together on September 23, 2026 and talked less about process than about where a game's world comes from. Ueda credited Another World with the idea that you can build a world for the world's sake, not the game's, and said ICO's hand-holding followed from studying its alien relationship. Chahi pointed the influence back the other way, toward Heart of Darkness and the shadow enemies in Ueda's games.","attributionJson":"[{\"source\":\"4Gamer.net\",\"url\":\"https://www.4gamer.net/games/426/G042651/20261005004/\",\"title\":\"You Can Build a \\\"World for the World's Sake,\\\" Not Just a World for a Game: Eric Chahi and Fumito Ueda Discuss Game Design [The Tenth Mosaic]\"}]","lintFlagsJson":null,"lintHits":0,"costUsd":0,"inputTokens":4677,"outputTokens":705,"status":"published","repairAttempts":0,"nextRepairAt":null,"factsAttemptedAt":1791526036,"createdAt":"2026-10-09T06:03:27.000Z","publishedAt":"2026-10-09T06:06:08.000Z","updatedAt":"2026-10-09T06:06:08.000Z"},"cluster":{"id":"c_b3ace6346be0864c80a38dc9","canonicalTitle":"ゲームのための世界ではなく，“世界のための世界”を作っていい。エリック・シャイ氏×上田文人氏が語るゲームデザイン［The Tenth Mosaic］","representativeArticleId":"a_11856bbee3c964757ecc6fa8","sourceCount":1,"writtenSourceCount":1,"writeAttempts":0,"isSolo":true,"entitiesJson":"{\"anime_titles\":[],\"manga_titles\":[],\"work_titles\":[\"The Tenth Mosaic\"],\"studios\":[],\"people\":[\"Eric Chahi\",\"Fumito Ueda\"],\"type\":\"op_ed\",\"domain\":\"games\",\"is_roundup\":false}","contentType":"news","status":"published","firstSeenAt":"2026-10-09T05:13:20.000Z","lastSeenAt":"2026-10-09T05:13:20.000Z","updatedAt":"2026-10-09T06:06:08.000Z"},"attribution":[{"source":"4Gamer.net","url":"https://www.4gamer.net/games/426/G042651/20261005004/","title":"ゲームのための世界ではなく，“世界のための世界”を作っていい。エリック・シャイ氏×上田文人氏が語るゲームデザイン［The Tenth Mosaic］"}],"entities":{"anime_titles":[],"manga_titles":[],"work_titles":["The Tenth Mosaic"],"studios":[],"people":["Eric Chahi","Fumito Ueda"],"type":"op_ed","domain":"games","is_roundup":false},"keyFacts":null}
