I did not need to include any 3d party lib into my projects yet, so I was quite lucky with the quick results and ease of use. But its still a shame if corona works that way, from an ideologiocal point of view.

I am always keeping an eye on other frameworks and decide before every new project if corona still fits my needs or if its better to invest some time and learn something new. So maybe I might switch to monkey code / unity / stencyl / whatever in the near future.
