As others have said, this is an EXACT port of the old game. I loved it on the pc as a kid, so Ill play this iPad version, but it sorely needs updating - modernize the GUI and improve the graphics!!!
As another reviewer said, you have to use the keyboard controls, which is a pain. It took me awhile to remember that you can skip a units turn using the space bar.
It also has a BUG that REALLY MUST BE FIXED - the "Loading" function (to ship or to wagon train) in the new world isnt working correctly, often it loads items I dont want to load. The drag and drop isnt working and a selection option doesnt come up if I hit "L" on the keyboard. Loading in Europe doesnt have this problem as the selection menu pops up correctly.
