I just found out this amazing video of a rail network created in transport fever game. I'm not a fan of sandbox games myself, I prefer to jump in the driver's seat and enjoy the environment that was already created by someone else, but this looks amazing. Just imagine combining something like this with something like tsw. It would be epic to create a rail network of your dreams, and then jump in and drive like in a proper train sim. A man can dream. For the impatient ones, the fun starts at 3:30.
So I bought the game and, I'm having a blast. It's so much fun to create your own railway. Like playing with model trains, but with more detail.
