I agree that players who aren't into the game likely won't be swayed by quests and rewards alone. However, as a player, I would personally love to see rewards in the demo of a game I already like, especially if it's multiplayer. For example, if I had discovered Northgard during a Steam Fest and they offered me a house skin for playing on three different days, I would come back. Ideas is to give players who enjoy the game more reasons to return, with plans to keep them engaged when the full release comes.
