The game is entertaining and runs smoothly on my computer. I have yet to have a problem with bugs.
Here are problems that I have with the game:
1) Can't specify hauling multiple loads.. can only be one commodity so if I'm hauling things to my factory which requires more than one input commodity.. it takes a few runs.
2) The AI of the competition is awful. They jam up the tracks with a ton of their own trains so that you have to disconnect from their track and lay your own with your own stations just so get your trains through.
3) There needs to be more overview information. I don't like playing a game where I have to keep paper nearby to make a list of where the demand is headed. The game requires a bit of guesswork as well.. I wish it would tell you what cargo will be given first priority when it comes to loading your train. This is probably my biggest complaint.
4) Overly simplistic business aspect. A little more depth would have added a lot.
Overall the game is entertaining and I played it a couple of weeks before I became bored with it. I would recommend someone to buy it.. but perhaps not pay full price.
