Possibly. But modularity and reusability still have
benefits even where only one author is involved.
On the plus side, the amount of library code actually
involved might be quite small. Many of the things
that require considerable amounts of support code
in traditional IF systems are so simple to implement
in Prolog that you don't really need library code
for them.

Could be, although I feel that the problems involved
with "intelligent" actors go a lot deeper than which
language is used to implement them.

Yes.

Can't say for sure (I haven't seen the version you mention)
but probably not. It's pretty basic - the author uses it
to teach prolog, not adventure game programming.
|> I wondr where else to find IF in Prolog?
I don't know - Merritt's book is the only place I've
ever seen the idea discussed, despite its obvious
potential.
