Hi Mohammad,
Unfortunately we don't have a tutorial on how you can setup a game like Travian or Tribal Wars but if you've specific questions; regarding particular elements or mechanics we are more than happy to help. Is there any particular elements about a time based mechanic that you're running into trouble with? Some of our documentation may also be able to help guide you in the right direction on this such as Scheduling Cloud Code for instance (https://docs.gamesparks.com/tutorials/cloud-code-and-the-test-harness/scheduling-cloud-code.html) I hope this helps.
Kind regards,
- Steve
