An open world approach is probably not in line with that, but what else can be done to improve the game?
And another interesting issue is that somehow the game is just not selling as well as it should... It deserves about 4-5 million IMHO;
Hm, interesting question...the first thing that came to my mind was: improve the tech! re-increase the shadow resolution, re-increase the texture resolution and enhance the texture filtering and work on the animations and their transitions.
But maybe this is not what you asked for
, so I for myself think that they should stay by the same formula...keep it as an 'action-movie'!
Some of the action scenes are really phantastic: fighting in a collapsing building was unbelievable for me and really one of the most memorable video game scenes
The action scenes and the fighting itself is for me flawless: every confrontation can be solved in many different ways - great!
But I definitely think that they should do something with the puzzle parts: for me it seems that they absolutely don't contribute to the game at all...in a hollywood block buster, many of those scenes would have been cut out!
Either make them more challenging, or skip them all together. As skipping is basically not an option...they should at least make them solveable by logic and not by looking into the diary! So as they improved the action combat part from UC1 to UC2, I hope that the improve the puzzle parts in UC3. But as Evan Wells often iterates in interviews: the most important thing for ND when designing UC is that they want people to finish the game...so with this goal in mind, they don't have to much freedom either?!?!
A bit difficult to judge are the platforming parts: this is very problematic, as difficult platforming often gets frustrating...so imo, the should keep the platforming as it is but use it to show of the graphics, i.e. to make some nice site seeing tours and incorporate some 'wow, did you see this' vistas!
And they really really really should include a full online coop modus for the whole SP campaign - this is an absolute must and should also naturally increase the sales of the game!!!
Regarding the sales figures, I don't know the numbers, but I know if the numbers were great I would know them!
Basically it is a shame and I really blame the PS3 crowd for being chronical non-buyers...but it is also obvious that the style of the game doesn't fit to everyone.
Increasing the sales would be very easy in concept if you asked me but would need a drastic change in game design: make the game realistic !!
Change the look from stylist to realistic...just imaging how this game would look like if ND opt for realism.
Change the combat from stylist to realistc: real sounds for weapons, no bullet sponges, brutal combat with screams and deaths!
Make platforming as realistic as possible: no 10 meter jumps while hanging in an ice wall.
Don't include 'fantasy' parts into the story.
Maybe even change the theme of Drake from 'funny lucky idiot' to 'sarcastic'?
