First you have to decide if you want to take a loan to build your ship. Here the gamer is being taught about monetary actions, something useful for nearly everyone in the world. There is also an aspect of geography in the game as you have to decide where to settle along with which sea route to take to the monastery. The game also shows how Vikings built ships and the possible crew members that would go on the journey with you. And before you leave on your journey you pray to the Viking gods so the gamer also learns a little about the Viking religion.
Its fun because the game allows you to have the power to make most of the decisions for your journey. What is even better for learning though is that the game holds you accountable for your decisions too. For example, I actually lost the game because my raiding haul was too small and I burned down the monastery before I left. The chief sent me off to go work on a cod fishing boat as punishment too. I could have done much better in the game and next time I play I will have a better idea about how to go about a successful journey.
In the end this game is very informational. It shows you historical and cultural aspects of the Vikings and it has you make life decisions such as how to use money. Probably not all games are as informational as Viking Quest because it is put together by the BBC, but after playing this game I can see more how video games can be a helpful learning tool for people.
