I recall writing of this topic before;
but anyway I thought I must write this:
You will find plenty of many kinds of items during the game;
but not so much gold relatively.
Thus many items are very expensive to buy.
Some additional free item slots should be added at merchants,
to ensure some trade option (especially, to enable some selling!)
at points when your party has no gold left,
and the main portion of all the gold available to be found/earn
has been already taken.
Additionally, there are some items that are vital to the overall
progress, but are relatively difficult to get;
especially the Lockpicks.
I think the total amount of lockpicks available should be slightly
increased.
