Gee can you tell me what your game is?

$^O =~ /mac/i match anything from 'mach', 'emacs' to
'ThisISANyThingButAmaCiNtosh'

In fact standard perl support MachTen. Although I don't use MachTen,
I'm pretty sure its $^O return "machten" or "machten_2"

In that case, what you really wanted is $^O =~ /^macos$/i

But that's plain wrong too!!
I use $^O eq "MacOS" because "MaCoS", "mACOs" etc could be anything.
I don't consider those variation Macintosh related at all.
