Platform control is not IP ownership: Roblox, Fortnite and storefront deals compared

A platform account, an experience or island, a store listing and the underlying intellectual property are different assets. Control of one does not prove ownership of the others. Roblox warns there is no official experience-sale system; Epic documents UEFN project ownership transfer; Steam, Apple and Google each operate their own application-transfer processes.

Build a rights matrix with rows for code, art, audio, names, trade marks, domains, user/community access, analytics, payment records, app IDs, cloud services, SDK keys and platform listings. For each row, identify the owner, governing contract, transfer mechanism, consent, evidence, completion owner and fallback.

This matrix prevents a common acquisition failure: paying for a successful product but receiving only repository access or a platform role. The definitive agreement and platform steps should close together, with holdbacks or conditions where a critical transfer remains subject to third-party approval.
