Train Sim World 4

Whilst Train Sim World 4 does the train sim part quite well, the world part is incredibly lacking - it comes with only three routes in the base game and the others cost significantly more than you might expect. All of those routes are in North America or Europe, even the DLCs, which would make it a much smaller world than the one I live in. If you love trains and have plenty of train sim money, Train Sim World is a good option for running routes. Just be aware that you'll probably be paying more than is reasonable.
