OpenTTD suffers from the same problem it has for over a decade: there's no real goal because the economic simulation is lame. You would expect that a game like this would try to simulate supply and demand and then your goal would be to satisfy unfulfilled demand by transporting goods, but the simulation in OpenTTD is completely disconnected from reality. Whatever transport networks you build, the game will magically invent customers for them. I put a bus stop in a town with 1200 people and soon 1400 people were waiting at the bus stop. It's trivially easy to make huge loads of money. Just put airports between two big, distant towns and watch as thousands of people line up to fly back and forth. Did they actually need to go there? No. Building the airport and assigning the transport route created the desire to fly between those two cities. If you move one of the airports, suddenly everyone wants to go there instead. In fact, by default, passengers in the game want to go from any station to any station. They don't even care where they go!

The game starts with a bunch of completely disconnected towns and industries. (How did the towns even get built and populated with no road connections? Why did the industries get created if nobody is supplying their inputs or consuming their outputs?) If the game had a real economic simulation that kind of setup would be completely unworkable. Although featuring simpler transportation networks, Railroad Tycoon 3 did a much better job with the economic simulation and the game.

So ultimately, I can only recommend OpenTTD if you just want a sandbox to build transportation networks in. If you actually want a game to play, or a reason to build those transportation networks, you won't really find it here.
