If it&#x27;s specific enough, you could even create a game using your employers equipment &amp; keep ownership &amp; copyright yourself (the Queensland government provides that as a specific software example here):<p><a href="https:&#x2F;&#x2F;www.business.qld.gov.au&#x2F;business&#x2F;support-tools-grants&#x2F;tools&#x2F;intellectual-property-info-kit&#x2F;browse&#x2F;employees-contractors&#x2F;ownership" rel="nofollow">https:&#x2F;&#x2F;www.business.qld.gov.au&#x2F;business&#x2F;support-tools-grant...</a>
