Gents, this is a discussion that comes back for each of the US City X products. And to be honest it gets a bit old.
I cannot go into too much details but it is not twice the development time, not three times, but much more.Just accept that as a fact even if it does not seem logical. If it would double the development time we would consider it, but it is not double, it is far more. If we calculate that for the previous products we would need to have sold three times as much of each, or triple the price. It is just not feasible. The product is as it is or it would not exist. Las Vegas was a exception and I am pretty sure we lost money on that one because of that.
So let's close this topic. No night textures. If that you feel that is not acceptable this is not a product for you.
