when you step back it looks good, but when I played it with some people the scale is very large. Took too long to get somewhere only to get picked off by extremely long distance. Its not fun when you dont see your assailant. And there are so many huge rooms with ceilings off screen that you can shoot down from. Also it doesn't make much sense, especially for your chaning of tracks, where a train would go one way only to turn 90 degrees no matter what, then another 90 degrees just to turn the train around 180 degrees.
