Issue report: Spacechem asked to install unspecified packages
I was just going to play SpaceChem for the first time (nice key copy UI), when gksudo popped up asking for my password to do an "apt-get install". As a sysadmin, being asked out of the blue to give your password to install unspecified packages instantly raises alarm bells.
If a game needs to install some packages, please make it obvious which packages it is going to install, and give me the option to do so by hand if I want to do so (which will also help for those not using Debian based systems).
It might be an idea to have any dependencies handled on the steam side rather than by the game itself. It's easier to verify that steam does things securely than every game I want to play.
