Lego Lord Of The Rings
When in Middle Earth you can not check...
a) what blacksmith plans you already found
b) how much Mithril blocks it costs to build
c) if you already have it built (at least the "treasure trove" reveals this info)
d) what abilities it provides
It would be nice to always be able to view these information in a menu similar to the Extras menu for the red bricks.
This would avoid many travels to the Blacksmith just to recognize you do not have the plan or not enough Mithril (a-c).
Additionally it would the make decision what to build much more reasonable (d).
