That means that after mining 20 ores you have to get rid of them before you can go on.
lol, sometimes the most obvious solution makes the most sense. Give ores weight, the more weight you carry the slower you dig, and once over your weight limit you will have to either drop ores or return to town. This should automatically limit botting dramatically with [i assume] the least amount of changing. You risk alot by dropping ores to mine longer and besides you will still not be able to carry it all back in one go if you do so........Packmules coming?

3- Nodes that originate on the floor will grow upwards, nodes that originate on the ceiling will grow downwards, and nodes on the walls of impenetrable rock will grow away from the wall. Ceiling nodes will be mined out upwards, leaving a cavity in the roof. Floor nodes will be dug out downwards, leaving a pit in the floor. Wall nodes will be reduced to a thin seam on the impenatrable rock.
Very initriguing idea, and i would love a world that are as dynamic as that. I\'m not sure i\'ve actually seen even single player games with that type of \'growth\'. Half Life 2 was revolutionary with its physics engine and even -that- was actually rather limited. [Imagine walls being rebuilt or acid actualy slowly \'eating\' through walls....]. So i don\'t know whether it\'s hard to do, put something tells me you need almost an entire engine for that. Plus if you can THAT in mines, why stop there? Building your own house with bricks jumps to mind.....building structures/statues and -anything you can think off suddenly should be possible. [and i\'m not talking about buying a \'predefined skeleton\' of a building like you probably get in other MMORPG, but actually unique building blocks]
The whole minerals and different types of metals which are mixed and treated in various ways [almot like an alchemy type of system] is very good. It\'ll certainly give depth to mining, although won\'t change the digging part UNLESS the above system is used OR
the focus is actually completly shifted from the digging but to the \'treating\' process. So ess
entially the digging itself is simply going to the right place and press dig and you dig 50 ores in one shot..done. The ores will not be very valuable, but after doing some mixing and matching and whatever \'tempering\' processes are available the ore can turn into sometihng alot more valuable.
i.e. you do not dig \'ores\', but unrefined \'rocks with gold in it\' , and then you need to refine and extract [almost like those golddiggers with their little pans next to the rivers and sifting the gold out of it] and then you go to some \'facility\' to do whatever else. Each process makes the item more and more valuable, you can of course \'sell-short\' without going all the way [i.e. gold bar, or golden bracelet]
but the profits will be alot less. Essentially being a miner in PS will probably then mean you need to go further and become skilled in say blacksmithing or jewelry making
