I bought the game on steam for 139 euros but i only have the testing facilty, Notihng else, Did i do something wrong or?
You can check on your Steam store page, what DLCs you've got & what have you installed / uninstalled This will show what you have - This will show what's installed -
Did you buy the base package. If you just bought dlc without the actual game itself, you won't be able to use them. And make sure they are downloaded of course
The DLC menu didnt even show up, that your in on the seccond picture i couldnt find, I havent bought any dlc just the game. As you can tell i am a bit of a noobie
What you bought is the upgrade pack for 13.99€ (not 139). This is just the base game without any route and DLC. It's meant for upgrading a TSW2/TSW2020 to TSW3 and being able to play your purchased TSW2 and TSW2020 DLCs in TSW3.
...Just an explanation that isn't very clear (the explanation given applies to literally any version of TSW) and is far down the page from the buy button for the upgrade pack, which has absolutely no context applied to it. It should say something like "Train Sim World Upgrade Pack comes with the Training Centre only. Other routes must be purchased separately or imported from past Train Sim World games." The explanation is not good enough, hence the existence of this entire thread. If I struggle to figure it out, having played Train Simulator and Train Sim World for almost a decade now, a new player can't be blamed for getting it wrong.
