Those aren't Sierra products.
Sierra On-Line's IIGS problems have been discussed at length previously.
Basically, what it comes down to is that their games are written in a
special game-programming language, which is in turn implemented as an
interpreter on each kind of computer that Sierra supports.  The IIGS
implementation of the game system did not perform as well as would have
been required for market acceptability.  Some people blame it on the use
of a high-level language (C) to implement the kernel of the interpreter,
while others of us blame it on the poor quality of the code generated by
the compiler that Sierra used.  In any case, a good implementation would
be considerably faster.  Sierra declines to allow anyone to work on this
without becoming a full-time Sierra employee, which of course rules out
the majority of qualified IIGS programmers.
