openage.desktop file:

Exec=openage %u
Path=.openage

Which no longer works since qml files are also expected to be sitting next to ./assets. On an installed system the qml files are in /usr/share/openage while the assets are in ~/.openage/assets. Short of symlinking the assets into /usr/share/openage and launching the game from that directory there does not appear to be a way to run it outside of a development setup where everything is in a single directory.

Seems like there needs to be some path discovery or somesuch.
