If there is an utopia flying around this thread, this is the "realism" one.
A computer game will never be reality. Cat people, stone ones, magic spells, those are only myths, unrealistic features.
Now, if you could start thinking about consistency in a immersive world, maybe could some valid elements come into the discussion.
The general balance of economy is not perfect in version 0.3 What a big deal. Some constructive suggestions, based on the existing settings might help improve it in the future, while considerations based on capitalism are refering to a realism rather relative in a society licing on medieval values.
Coins are melted in the lower levels. injected into the economy, and they go in players pockets, and many players are living the world with full pockets, so more coins are added.
As usual in PS, it's pointless to post "this is unrealistic", "this is not complete"...it's so by design.
And as usual, any balanced suggestion can be submited in the whishlist forums.
