Word Battles

Make your own crossword. Each turn a player chooses a letter, which both players have to use. Who makes the best words and scores the most points? Two players have separate sectors of the game "board" (with a screen hiding it from the other player's view), each 5x5 squares in size. The players take turns announcing a letter that both have to place in their grid. When the entire grid is filled, players count their points (as in Scrabble, rarer letters count more; also, there are bonus points for words with 5 letters). The player with most points is the winner.
