In many ways, I am extremely disappointed that this series had not reached what I felt was a higher potential, but it also delivers a frantically great experience that will have you entirely immersed in the fascinating world it presents.
Throughout much of the game, the humor that was once so charming crosses partly over to being crude as well as insensitive. And, the opportunities they had to develop these characters more, for us to see them thrive and gain more through their experiences, to grasp the reality of their situation, then to grow wiser as a result, was all missed. At its core, all the characters are static. Rather than growing and being the preferable dynamic characters they should have been, they learn nothing and remain the same. It really is a shame, because all these characters are so likable and interesting. Instead of development, we had been given an abrupt ending that very poorly tried to end the series with an open note, but absolutely failed to do so.
The gameplay is improved, however. The first section is very well-done, and I found myself enjoying it far more than any other part of the series thus far. As the game went on, it became progressively more cryptic and difficult, but still managed to maintain a somewhat fresh twist on the point-and-click formula. The settings and environments remain beautiful, and the animation never failed to impress.
The Deponia series, despite its shortcomings, proved to be a very memorable trilogy of games filled to the brim with a sense of wild imagination that spurred my mind alive. It possessed additional potential that could have propelled it to become a true classic, but as it stands, I feel it is still well-worth your time if you're even remotely interested in this type of genre.
