Hi, me a my friend have been playing the game religiously for the past few days and were both thinking that the game would be alot better if it had sailing. This could be achieved by implementing a larger ocean around the game world maybe some places to discover like a random generation of islands outside of the main 2. This would then allow players to not only explore but add more to the late game enabling clans and such to build long ships for exploration and raiding. While early game players could build fishing boats and go out and fish to gather more resources. Not only would it expand the game as im sure you're all aware sailing was a huge part of Viking culture as was exploration, raiding, fishing.
Just a thought,
