It'd be nice if they released the code to their old DOS game catalog. Probably piles of 16 bit assembly but it'd still be nice (assuming they still have it)
It took a very long time for the source code for e.g. ZZT to be published, precisely because they apparently lost the code. https://github.com/asiekierka/almost-of-zzt Even then that had some third party comments removed from it.
