Snowball Fight (2002)

From the back of the box:

Players will find themselves wrapped up in a game of luck and strategy (instead of a scarf and mittens) as they attempt to hit their opponent with Snowballs and the insidious Dipsy-Doodle. Avoid getting wet by playing cards such as Powder Ball and Bad Aim that affect your opponent's chance to hit. With the roll of a die and a little luck, you'll send your opponents home for hot chocolate and to change out of their soaked clothes.

This game is basically a "take-that" style card game where players take turns targeting each other with various "damage" inflicting snowball cards and rolling a die to see if you hit. Targets can defend by playing various cards that affect the die roll and sometimes allow a counter-attack. Much more friendly for young children than similar games such as (e.g.) Lunch Money. Most clever aspect of the design is the round snowball-shaped cards.
