Too bad Sony's tendency to take down anything based on an existing IP, even those works protected under Fair Use, will likely result in all that hard work being for naught.
I think everything that's been taken down has been clear copyright violation with exact names and scanned pictures from comics and so on. This looks like it's probably on the edge of that, unfortunately.
Where the hell did that sackboy costume come from though? I've never seen a costume which wasn't built on top of Sackboy's basic model. Is it DLC I missed?
