Same problems exist. Single quotes do NOT interpolate, meaning the value
of the variable is not replaced, the variable name itself is being used.
So Perl is looking for a file called $Player{Location}.pl which probably
doesn't exist. Double quotes DO interpolate, but when you don't need to
interpolate use single quotes. So,
$Player{Location} = 'Inn'; # single quotes are fine
require "$Player{Location}.pl"; # double quotes for interpolation
Theoretically this should work if I remember 'require's specs correctly.
Though these days I would switch to 'use' and bring in both libraries
unless they are really huge, and not worry about the run time consequences.

Again, you would need to use double quotes, but in the above you might
be able to get away with or may be required to avoid stringification. So
either,
"$Player{Location}"::HTML();
or
$Player{Location}::HTML();
Either way single quotes will NOT work. The above also assumes that you
have included the proper package statements in the required library.

Not the vars that matter, it is the quoting.
