That was people, try comparing train engines. Johnwhelan is right, TRS is probably equally capable as is KRS, but most choose not to take advantage of it like he said, especially when it comes to things like people. When the 3rd Trainz Classics installment comes out, maybe you should do a side by side comparison there. Also, KRS is more like the style of MSTS, being more "point A to point B" where Trainz is somewhat more model railroad oriented. The KRS content seems more weathered, and as good as it looks, Trainz doesn't look too bad either, and there's so much content for it, so I'm staying with it! Like I said before, if backward compatibility with MSTS will be in KRS, maybe I'd be interested... maybe.
