This is a bit spoiler-ish, but I just had to share it.
Cinders' actions during the game determine what ending (and what variant of that ending) you get. For example, Cinders can obviously marry The Prince and become a queen, but what kind of queen she becomes is determined by what you did during the game. Is she going to be good but too naive? Machiavellian but competent? Or maybe devilishly evil and sexy, like in the pic below:
There's going to be a special image for every variant of every ending in the game. Collecting them should be lots of fun.
Love it...very Mucha-esque :)
