Wordplay is a wonderful game, with some comparisons to both FATE and Burning Wheel, and some brief glimpses of HeroQuest. It it based on "traits", which can be skills, relationships, or aspects. Each is rated on a scale 1 to 12 dice, unlike FATE where Aspects are un-rated, but skills are. Challenges are always tests where the character's dice are rolled against a pool of difficulty dice (seldom a fixed obstacle). Each die is scored success or fail, and the higher number of successes 'wins' the Challenge.
Unlike FATE or BW, there are no 'fate points' or 'artha' -- point obtained during play by good role-playing and used to boost capabilities. All such rewards are reflected in experience, which is used for character advancement.
Wordplay gives some good and flexible ways to deal with Powers -- ways of implementing magic, psionics and the capabilities of the divine. Fans of HeroQuest may recognize some elements here.
All in all an excellent product -- well worth paying for, and the free Core rules a real bargain.
