Evidence claims:
- [sourced_fact] The GGG product terms apply to individual use, including commercial use; corporations are outside them and must negotiate separately. · locator: GGG製品利用規約 第1条（対象）1項 · source: https://rpgmakerofficial.com/support/rule/
- [sourced_fact] Article 7 prohibits training generative AI on all or part of the GGG products by a method the company has not permitted. · locator: GGG製品利用規約 第7条（禁止事項）2項6号 · source: https://rpgmakerofficial.com/support/rule/
- [sourced_fact] Material terms: purchasers through the company's approved channel may use the bundled company materials in works made with the product or with other game-making tools, but modified materials may not be used alone commercially and the materials may not be distributed. · locator: 附則 素材利用条件 第1条 · source: https://rpgmakerofficial.com/support/rule/
- [sourced_fact] Extracting company materials from user software to reuse in other software, free or paid, is prohibited as a distribution condition. · locator: 附則 ソフトウェア等頒布条件 第2条6号 · source: https://rpgmakerofficial.com/support/rule/
- [sourced_fact] The RTP page: the runtime package (graphics, music, DLLs needed to play games) is free to use but secondary distribution is prohibited, for profit or not, without written permission. · locator: RTP page, 配布について · source: https://rpgmakerofficial.com/support/rtp/
- [sourced_fact] Games using RTP materials need not include those RTP data on the finished game disc. · locator: RTP page · source: https://rpgmakerofficial.com/support/rtp/
- [upstream_claim] Research review verdict at export: reviewed (as of 2026-10-17). Recorded by the research pipeline, not a hub review outcome; evidence.review stays unreviewed until an independent reviewer records one.

Rights:
- sample_assets: license=LicenseRef-GGG-product-terms-ja hosting=restricted redistribution=prohibited modification=restricted training=prohibited · Bundled materials and RTP (component corrected by L07 from other to sample_assets): GGG product terms: individual use including commercial; bundled materials usable in own works by legitimate purchasers, not distributable or extractable; training generative AI on the products without the publisher's permission is prohibited (Article 7, item 2-6). The publisher's RTP is free to use but may not be redistributed without written permission. · evidence: https://rpgmakerofficial.com/support/rule/
- other: license=LicenseRef-GGG-product-terms-ja hosting=not_applicable redistribution=not_applicable modification=not_applicable training=unknown · outputs: games made with the product may be used commercially by individuals; games using the RTP need not ship the RTP data, so players need the RTP installed or the creator must rely on the materials terms. · evidence: https://rpgmakerofficial.com/support/rule/, https://rpgmakerofficial.com/support/rtp/
