I think what they needed to do is not try to make it look "older" or "more mature" but give it a more unique "personality".
The Sorcery that i imagined had towns and villages, with intelligent puzzle solving, platforming and an engaging story.
They showed it at E3 and everyone was taken by the mechanics and how well they seemed to work. It's like they just focussed on the spell casting mechanics and forgot that they actually need to make the rest of the game to go with it. Sorcery should be more than just a tech demo to show off what can be done with MOVE. I do hope that the producers at SSM, and the developers themselves understand this, and if the actual game is not yet there they should take it back to the drawing board and start again to ensure that when they reveal the game the next time, it's obvious to we the consumers that the game is indeed there and it's solid and engaging.
I don't mind the game's new aesthetic. I think it's good that they tried to move it away from the generic "harry potter"-esque look. However now that they have this new look and identity, they need to sell it to us gamers by revealing more about the story, characters and world that you'll explore throughtout the course of the game. We've already seen all the spell casting mechanics, so its useless showing those to us again. I just think that the people in charge of these game reveals have no sense at all. Thinking they can sell a game like Sorcery to the core audience through a short list of bullet-points about the combat/spell-casting mechanics... it's just not the way to sell a game.
I'm quite disappointed really, however i hope that they both have much much more of the game to show and that they do indeed do so in a way to rekindle my hype. As the silly "hey gais, look how i can flick my Move wand to shoot different coloured bolts at gremlins in a weird-looking psuedo-fanstasy setting" marketing message for this reveal actually stank and made the game appear worse than its original reveal.
