Most (nearly all) time-travel related stories, movies, or games are riddled with inconsistencies or paradoxes - usually the result of the writer not thinking the entire concept through. Continuum is the exception that proves the rule. A logical, wholly consistent world in which time-travel is a reality, and it is actually playable as intended! (As long as you don't mind keeping what is essentially a character diary to keep track of all the time travelling.) I read it cover-to-cover the day I bought it, and I still can't get it out of my mind. Easily _the_ most compelling RPG I have seen in a long, long time. Buy this game, you won't be sorry.
