If you want to try O.D.I.N. on Let's Role, there is nothing left to set up. The demo table holds the mission “Das Haus am Stausee” from the Quickstart, two scenes, the four ready-made agents to import into a new character, and two handouts the GM reveals at the right moment. The table is in German.
A Let's Role account is free. The invite link takes you to the table.
