Why would you Uninstall a good game? It's on my phone, no matter if I'm done with it or if I'm low on storage space.
It happens, though the top comment seems to be worried about a lock on files open in an application, which is a pretty common thing to keep you from breaking active things on your PC even in Linux...
Though a root user can easily override that while a Windows Admin can not.
Even Firefox has a lock in the directory that makes it impossible to delete, even as an admin, while the browser is running.
