[Selling resources/ore/oil/tiberium/crystals for a volatile & changing market price]
[I think that the price/value of a unit of the resources e.g. a barrel of oil or a crate of ore/tiberium/crystal shouldn't be standard and always the same. This price should be depending on a marketprice which can go up and down like the oil price on the stock market in real world. So if there is a big demand on the marketplace for ore/resources than the price is high / going up if there is too much ore/resources available to the marketplace the price is low/drops.
So you could add a small graph of the marketprice to the game and always when you are about to click the button to sell a certain amount of ore/resources it the button will show you the total amount of credits you will get at that moment. You could also add a automatic selling point that you want to sell an amount of ore when that price will come up. Of course you opponent/enemy will use the same market(place) an the price will drop immediatly because the market is full. I think it still has to be tested in which total or percentage amount the price should be able to change from the average price. +30%/-30% or even +50%/-50% ]
[Harvesting resources still will be important to gain credits to build everything, but gaining/collecting more resources than your enemy will not lead automatically to more credits (than your opponent) which many times also leads to big advantage towards victory.
Instead of collecting much resources by many harvesters(I use 3-5 at least) and ore refineries(I use 3) its also possible to collect less resources with less harvesters(1-2) but selling the at a good / higher price than your enemy did.
1-This way also a rush on resources is less effective.
2 -Also a rush on your enemy's harvesters (=taking down the harvesters of your enemy) will be less effective because you still can have some resources in your depot(s) which he can sell for more credits that your enemy.
3- Using an engineer which occupies your enemy's depots and can steal an amount of resources(NOT credits)once or a percentage of the sold credits (until he is found (inthe building) & killed by an engineer of your enemy) could add more gameplay.]
4- In multiplayer you could have an option to trigger a standard price of resources or a changing marketprice.
5- This kind of developing marketprice of the ore/resources would also have effect on how fast everything could be build and could slow down many 'rushes' and add time for the real base builders who like to turtle up (a little bit) before waging war because he will get very less amount of credits at the beginning and also when he sells too much in a short period which will slow down his productions of small price units that are mostly used for a rush in a game.
(I personally hate it when a tank or even buggy rush destroys my well planned & placed base within a few minutes. If this is so possible why the having defense buildings walls etc. and other advanced units & abilities in the game if I can't even use them because I am slaughtered by a 12 year old kid which like to rush with very simple units and don't have to think then a liitle bit more strategic if he would have allowed me to setup my base. Like in chess. The Queen and all the others are not moved at the very beginning.)
1-I admit that this will add another level/dimension to the game which is not combat but again some (micro)management which could need some more attention and distract you from the classic battlefield.
But you could implement this game-feature very simple with a graph bar an a sell button and even adding an option for an 'always sell price' setting.
2- There is a (very) small risc that this feature would have a to big sideeffect on the combat / battlefield or even the outcome of a game by a player that uses his economic power an cleverness on selling resources and so making the other player impossible to gain ground financially and so not to allow him to build his army.
3- I must admit I am not sure what the negative (side)effects would be. If somebody knows a good one and also how maybe to solve it / take it awya i would be happy.]
I don't have any additional media at the moment for it.
Forgive me my bad english and any typo's.
