Yeh, if you're talking about web-based games (and I assume you are) Perl doesn't make a good front end. Perl can, however, make a good back end, managing users and global high score lists or whatever.

Here's two games I've written with a JavaScript front end and a Perl back end:
Bubble Crack (kinda big)
Burster (kinda old)

Incidentally, If you are interested in doing the front end in JS, I've written a cross-platform, cross-browser library for dealing with layers:
SmartLayers

I write the code while the master is away!
