I've heard it's not very popular, but I believe that requirement only exists because users of other distros may not have the dependencies contained in the runtime installed on their own systems. There's a possibility I could just ship the Debian build without them checking, and it'd probably work for most people, but I know there will be those few who don't have one or both of those libs installed who leave a bad review because it "doesn't work". When I get bad reviews, they should be about how the game sucks, not about the game being a broken scam.
