I don't know how I knew this

but knew the South Park Episode where Kenny has to die to save heaven was based not only on the real life issues of Terri Schiavo having to die to save heaven, but also the existence of Christian video games.

A Christian video game. While video games might be fun for a while, I'm not sure it's going to be a good way to cultivate goodness, whatever the religious themed game.

OTOH, I suspect that first person shooter games can train someone to be a, er...first person shooter.
