I've ridden commuter trains many times over the years. UC did a great job of capturing the feel of a train ride. It might not be the most exciting but it is amazingly immersive.To each their own I guess.
To me personally (and as a huge fan of the series), the train does nothing for me. Unless there's an incredibly low wait, i'll never take it for park-to-park transport. I have feet.
I guess i'm just not that up on HE as some seem to be.
