I think you're right in the scenario there was no human involvement in design. my guess which may be naive is that the tool use will be mixed. You may see gen AI used more for placeholder assets for example. I also think the landscape is shifting to the point codegen is acceptable in those circles.
If there is mixed usage of AI and human design then like the article said those components generated likely aren't copyrightable but the specific way you cobbled them together could be and that wouldn't need much change it seems. I'd like to follow the revenue anyway, last article I read was from about 6 months ago that steam AI-gen declarations accounted for almost 700million in revenue but it was unclear then to what extent ai tools were used (https://www.gamesradar.com/games/steam-games-that-openly-use...)
