Many a videogame has been followed by a lame knockoff that apes the original. Something's surely missing from each imitator described here—specifically, one letter of each game's title. (Tip: The digits in parentheses indicate the number of letters per word.) For example, the clue "This toe-tapping rhythm game is all about survival of the fittest (5 5 9)" would net DANCE DANCE EVOLUTION. The omitted letters spell out a description of these releases.
