I mostly agree, but what's wrong with Perl/Tk, what with its GUI widgets and Canvas for drawing stuff on? Of course, while you might have fun in Tk with vector drawings and static bitmaps (remember how we all loved mostly low-rez Wizardry on our Apple IIs?) you probably won't find an interface to OpenGL
in Perl. Oh wait. You will. *grin* (and no, I've never used it, so I can't actually say that it's worth a look).
And if those engines exist with C interfaces and you gots skillz, maybe you'll be the hero by writing the XS to make them accessible to Perl. But frankly, I doubt a scripting language is a good place to write "action" oriented games with polygonz running all amok. But Perl makes a great place to implement an interface to GNU chess or a networkable or mildly AI'ed strategy or card game.
Besides I seem to recall a recent article I read where the most popular computer games were Minesweeper and Solitaire, so maybe the interface isn't that big of a deal.
