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.

Ms. Pac-Man is the lady-friendly follow-up to Pac-Man. It's the same basic dot-chomping, maze-navigating concept, but it's expanded. There are now multiple mazes, the fruit hops around, and the cutscenes are slightly more elaborate. Oh, and Ms. Pac-Man has a bow on her head. Like the other Namco releases for Xbox Live Arcade, Ms. Pac-Man is a straight-up emulation of the original game with no additions beyond an online scoreboard, some achievements, and colorful side graphics that surround the emulation. If the idea of a bare-bones emulation of Ms. Pac-Man sounds like it's worth five bucks to you, then you're in luck. But the standards for Xbox Live Arcade are a bit higher than what this game offers.
