There is a social comment somewhere in the population explosion of sex games. This one, which is a sort of raunchy Clue, is relatively creative; players draw cards dictating a setting, props and personalities and then ad-lib fantasies around the situations ($14). Ecstasy involves the shaking of dice, moving to instruction squares on a board and, if you’re playing according to Hoyle (or maybe Shere Hite), a lot of other stuff. The most printable order is “Do a sensuous dance for your partner” ($12.95). Pornopoly (board version, $12.95; computerized, $29.95) includes such instructions as “Play doctor. Conduct a thorough physical examination of the player on your right.” Better you should try a hand of Old Maid.
