Interesting approach, but worth noting, the developers make their games on artistic merit and gameplay enjoyability. The trophy list is the last thing to fall into place. It looks like they didn't bother too much with the traditional trophy structure. But to be fair, who really cares, it will be an easy plat which will enable you to focus on the actual important aspects, y'know, like the game itself.
Also lol at the people throwing their toys out of their prams and losing interest because of the trophy structure. Here is a thought, play the game and enjoy it. Then think about how lame the trophy list is to you. I get that trophy hunting is important and admirable, but to react negatively to a game before we have seen it in all its glory, based purely on its trophy list is pure insanity.
