i dont remember it well but from what i do... you started out as one of the knights of the round table and had to goto the castle... i think on the "world map" enemies used to move around or be on spaces and when you got in fights or w/e it would be kinda like a fighting game aspect...
i know its kinda a really really bad desciption... if i think of anything more ill report
for some reason i keep thinking its called constantine... not really sure...
