It's from Phantom of the Opera, of course. Keenly aware of its source material, the game opens almost by establishing the player's own understanding. I, for one, enjoyed the possibility of a modern remake - how do you maintain the mystique of Gaston Leroux's Phantom when everything, it seems, can be found on the internet?
Structured in three short acts, with broad-strokes choices, Phantom casts Christine Daae in quite a different light. I found it interesting that the choices given the most granularity were the emotional ones, not the moral ones.
Overall an attractive adaptation of a story one not usually remixed (as much as, say, Sherlock Holmes or Lovecraft).
