The preview is positive, although I must politely disagree with HardcoreGamer's memory of The Curse of Monkey Island as a "3D game." They also note that we still don't know for sure how many episodes Duke Grabowski will consist of:
The game is poised to be episodic, with the potential for three to five episodes. Why is there a range of chapters? Well, the team obviously would love to bring Duke’s tale to completion, but they simply do not know for certain how much interest there will be in the game post-launch. Right now Duke Grabowski, Mighty Swashbuckler Episode 1 is prepping for launch this fall, and Episode 2 should follow shortly thereafter. Beyond that, though, Duke’s fate is in the hands of players. If a fanbase appears around the series then we’ll be sure to see how many more episodes appear down the line.
