Somebody mentioned the choppy scrolling on one of my game play streams of this. The answer given is actually pretty easy to understand. For one, all the other versions do the same due to hardware limitations. But it is also required so that when moving objects you are on a direct grid of movement. If there were smooth scrolling apparently it would cause major issues with trying to line up objects etc. where needed.

One thing that is pretty cool about these versions that have the overhead maps that isn't often talked about, is that you can still play the game in overhead map mode. Makes it a bit quicker to cover larger sections of the map if you don't have anything obstacles to mess with etc.
