First and foremost, thank you for creating this project on LEGO® CUUSOO!
We've looked into the possibility of producing a set based on this licensed property (Sonic the Hedgehog (Green Hill Zone)), and since another company has the construction toy license for this IP, we can’t pursue this further as a potential LEGO set. We're sorry to be the bearers of this disappointing news.
With any IP on LEGO CUUSOO is that there is the potential of a license conflict, either with an existing license or with a competitive licensor. Still, we think it’s better to be open and allow for possibilities, knowing there will be "no" answers along the way, than shut out the potential of IP-based products altogether. After all, just because this project isn’t a possibility doesn’t mean all IP projects wouldn’t be.
We've archived this project now since we know it isn't feasible. Your project will remain visible on LEGO CUUSOO, but in a status where it can no longer be supported or commented on. This way fans can still admire your creation.
Opening ourselves to new product suggestions invites popular ideas that don't always work. We are grateful for the spirit behind projects like this Sonic the Hedgehog (Green Hill Zone)project and for the opportunity to be challenged. It keeps us sharp and looking toward the future of the LEGO brick. We hope to see more projects from you soon.
