Regarding crafting. Would it be interesting if a random skill/reaction event popped up while crafting an item?
For example it could be something like a progress bar pops up. In the middle of the bar there is a marker to denote a "perfect" score on clicking/pressing a particular button at the correct time during the progress of the craft.
There is a similar system in Fable 3. Check the picture as an example of what it could be like.
Succeeding would give a better chance of a critical craft and would give players a more involved input than just selecting materials and pressing make.
Let us know what you think.
