Just having gone through both games and their “almost” tremendous impressions on me inspire me to write a comparison between them.
1.The Story (and the entailed environment)
That is the excuse for us to start a game. To say the truth, I am not surprised at all about the story of Divine Divinity. I dont complain the idea of a lone hero striding on the quest of saving the world, that is a sheer inflexible (and encourageable) formula (seem Beyond Divinity changes that). I do complain about the heavily-Tokiennian-influenced aspects of the story (and those of a heap of other games). In contrast, Lionheart offers an absolutely different approach (most original ever, as far as my knowledge is enlightened), that is Real history of Mankind distorted by the sudden appearance of Magic. Thus you will see how Real people, real events such as the Crusades, the Black Death, and even the coming of the Messenger Jeanne d’Arc (Jehanne in the game) are affected by Magic and Magic-wielders and the way they react to them (E.g. heresy-hunter like Tomas de Torquemada and the Immaculate Jeanne loathe Magic whereas some open-minded geniuses such as Leona da Vinci or Galileo adopt magic for the common good). Some of your newbies may be stunned, what? even I will meet da vinci?
