With closed-source binaries the argument for static linking is the strongest, IMHO, or at least shipping all the required shared libraries and LD_LIBRARY_PATH that in. The amount of times I've had to muck about to make a five-year old game work on a current system is somewhat bonkers, and I would never expect someone unfamiliar with shared library details (i.e. a normal non-tech person, or even a tech person not familiar with C/Linux) to figure all of that out.
