Trivia games have an enduring popularity. Most of us, inherently, want to challenge ourselves, flex our brains to see what we remember and, not coincidentally, show off a little bit. Thanks to the proliferation of portable DVD players, GameSnacks, a new line of travel trivia games from Snap TV, allow you to be ready for a contest wherever you go.

Kids Trivia was composed by kids for kids, with topics that include cartoons, pop culture, and toys. Family Showdown lets youngsters play against adults, with both groups able to play at their own level. Pop Culture, made for teens and older, covers musicians, celebrities, and scandals. Gender Wars pits the guys against the girls on such subjects as makeup, fashion designers, automobiles, and sports.

You've seen bullets fly and buildings explode before, but not like this. In an effort to perfect what we call "gun porn," Criterion Software/EA has developed a game in which simply pulling the trigger is an exercise in excess. The story? It doesn't matter. What matters is spraying bullet casings across the battlefield and crushing your enemies with rage and rubble.
