i am not entirely sure which versions but it is great fun.
Vampire: The Requiem is new. Vampire: The Masquerade is old.
Werewolf: The Forsaken is new. Werewolf: The Apocalypse is old.
Mage: The Awakening is new. Mage: The Ascension is old.
Plus there are a number of older games that haven't been updated yet - Hunter, Changeling, Mummy, Wraith, maybe one or two I missed.
By and large the old ones are better, in terms of background at least. The new games are a little watered down, designed to focus more on the players and their actions. That's fine and all, but it loses all the global conspiracies and apocalyptic themes of the old games.
Well, save Werewolf. W:tA got a bit silly, with Pentex and all. But I miss the Camarilla, Sabbat, and most of all, the Technocracy.
