I would love to have the cursor icon to show moment when the your moving the character around and also please have better dialog system, why not just have done like the old fallout style where you see the character and voice acting and animation when speaking to certain characters...

I would also like to see a interface for crafting where you see the ingredients you have gathered and have place them in a certain order for the items being made that would be useful for Potions and cloth armor...

I would love to see a mini game when smelting or crafting Iron armor...that one right there could be fun or frustrating at the same time though...

If there's more things that I can think of I will post it down here in the future...

Cheers and have fun (that includes developers as well)
