This is what happens when things are taken out of context. How about we wait and see the final product? As an observer, I love seeing the game's building blocks coming together, iteratively, formulating the vision with greater and greater precision with every pass. Truly inspiring.
Or an actor doing a fake menacing voice is nothing more than .... an actor doing a fake menacing voice. Lets take your clearly enlightened way of doing things which is basically to want no criticism of any product until it's finished. If we take this Broken Age game for example, I would imagine the vast majority of the people working on it only have an extremely narrative view of the whole thing. Do you think the small minority of staff who are seeing the bigger picture want no criticism of the game being made? I actually think it's the complete opposite. Quite often the only way good products become good is because of the avalanche of critical evaluation they get whilst being made.
