Hi everyone, I purchased this game on a whim years ago (I love sims), and haven't really played it. It's been un-installed for quite some time, but a recent surge in a love of trains in my 4 year old son made me want to install it, so we can drive trains together (fyi, he LOVES it.....especially the cab view, as he can't see the cabs of our local subway and it drives him nuts). Long story short, I would like to update to the most recent version, and would like to check out some of the player made content, but it seems I am getting conflicting info, do I need to purchase a first class ticket? Or is registering my product enough? Am I looking in the wrong places? Thanks in advance for your answers.
