There aren't a lot of Jews in video games. This is something I've always found interesting—considering the disproportionate number of Jews in the world of film and television—but not particularly unusual. Jews make up less than 0.2% of the world's population, so it only makes sense that we'd be in less than 0.2% of the world's video games.
Still, as a self-identified "pretty big Jew" who, like many Jews, both mocks and cherishes his culture, I've found a lot of resonance in games like The Shivah, the point-and-click adventure about a struggling rabbi. Less so with B. J. Blazkowicz, although there's always something special about mowing down Nazis. And I've always wanted to see more games explore issues in Judaism: there's a veritable smorgasbord of topics worth discussing, from intermarriage to fundamentalism to the difficulties of maintaining a Jewish identity in a very non-Jewish culture.
