TouchArcade: While I love blockbuster gaming as much as the next person, there's no question that the ever-increasing budgets and thinner margins have made the whole upper-end of the video game business disappointingly conservative from the player's point of view. Iteration is great. It's how games have come as far as they have. Yet, as an exclusive diet, playing it safe can sometimes be a little bland. It's a good thing we've got smaller developers who can afford to take risks on crazy ideas, because without such occasional spices, the hobby would be a lot less interesting. Dark Echo [$1.99] is one of those games that simply couldn't exist under the traditional model, but I'm ecstatic it does.
