Not bad. I shall probably buy it anyway. Not entirely sure if its an improvement over EA Railsimulator is graphically, although not especially interested in that. What Id like to see is decent signalling, timetables, operations, super elevation of track and multiplay, where one person takes charge of part of signal operations.
The Mk2 Patch addresses some of the signalling problems in EA railsimulator and they have got super elevation working behind the scenes. Whether a US simulator can deliver accurate UK operations remains to be seen, but I remain open minded and supportive of all software, including the forthcoming Trainz classics 3.
