Tomb of the Dragon Emperor's six levels will take most players somewhere around five hours to complete. There are a bunch of unlockables in the form of concept art and the like that you get for finding hidden artifacts scattered throughout the levels, but it's hard to imagine anyone being compelled to go after that stuff. There's something especially disappointing about failures like this. All the elements are here. But every last one of them is handled so poorly that the end result is a game even the bravest of adventurers should run from...screaming.
