as it stands right now , there is no incentive to purchase silver at its current rate
Many many ways to accomplish this...
The price of silver and availability to earn it in game needs a better balance... lower/higher buy/sell prices..rareness of drops etc.
Boston stall with more items of necessarily... seeds and 3 iron bars (the only things currently required to advance further ??, but once a player or few have this, the in-game economy turns the tide) ... from what i've read, this is expected in the future... the rest just seem to be perks that one truly doesn't need
And another idea, might be something along the lines of the Bibles sold for silver in Boston having no diminishing returns when used....that alone could bring silver prices in line with HUGE incentive as things currently stand.
example: Sure right now non-paying players can sell things and earn silver, level skills..etc ... but not at the pace of buying silver for real $ to get something with no penalty.
I understood one of Brother Beans past comments on why the learning ability would be put into place was to prevent players from using the same items over and over to level, to mix it up and I assume create a challenge and slow the pace.... well right there is something of an incentive one could research into a fair way to charge for.
i like Moo's idea of bigger purses, a bigger backpack would be nice to
perhaps a weapon with +yellow bile ?
All in all, it needs incentive to get players to buy silver for $ and the ideas are countless, i look forward to seeing how it all turns out.
