I'll agree with Dan in saying that Headhunter: Redemption is a better game than the original and a good example of how developers can implement improvements to produce a quality sequel. But in all fairness, the developers still haven't quite nailed it.
While Headhunter was a good game with several major flaws, Redemption is essentially the same game with those flaws removed, leaving, if not a great game, at least a very good one that stands head and shoulders over the original.
I think Brad's assessment of the game is generally accurate, but I cannot match his enthusiasm for Headhunter. When he claims it is the videogame equivalent of a Van Damme or Steven Segal movie, hes right. I, however, don't consider that a compliment.
If someone were to ask what the "Holy Grail" of videogames might be, one likely answer would be "A perfect blending of Hollywood storytelling with the player interaction of Silicon Valley." Like the Grail itself, this goal is currently (and may always be) out of reach. Developers made several attempts over the years, meeting with varying degrees of success.
