.PAK files.
PAK sounds like the SFX version of IBM's PKARC. If PLAY *must* be in PAK
format, then it is capable of unpacking itself. PAK also sounds like a useful
utility for people to use on their own, so it should be uploaded, too.
However, other than the PAK program itself, and any programs that have legal
restrictions limiting them to PAK, ARC should remain the standard archiver.
Follow standards except where legal or technical reasons force an exception.
If there are too many exceptions, THEN look at changing the standard.
ARC is easy enough to use. I support it's continued use for all non-limited
(by legalistic reasons) files.
