the contracts available to you basically depend on your reknown. We are filling in more and more contratcs with regular updates from now on, so you will get more to do.
Tip: You can accept a contract, negotiate payment and then say you need some time to think about it. This will put the contract on hold and you can return to it to finally accept or you can just click on another contract.
It would be wonderful if there was a short summary on first screen when you select a contract that said what it was “kill orcs at location X” for example, and then a “go back” button in the bottom. That way i can quickly say what it is that i just found, and i can go back and save game before i do other stuff.
