If people say they don't buy it because of the interface, well, we have to accept what they say, but for me, I think there is another reason as well, and that is to do with HW APPEARING to be being VERY complex to play.
But in reality it is a simple as any game you will ever buy........click, draw a line, select a order, it does not come any easier than that to operate..........once you learn the basic commands for a few games, not worrying about what is happening in detail, then you can move on and play it for real.
I suspect a lot of people are looking at it and thinking what does this mean, what happens if I do that, why does this not happen etc etc etc and expecting all the answers in the first hour.......it takes months and months to understand all the minute details of what is happening and why......not a few hours.....but a few hours is all it needs to get things moving, then learn the finer details as you progress deeper and deeper - that is maybe the problem, people don't want to invest that time, when they can smash and crash their way though NTW.
There are two interfaces to chose from, not many games offer that.
If there was a third one, would people rush out and buy it ?.....maybe, but maybe not.
I still use the OLD interface and it gives me everything I need to know.
