I have never asked for corporations to produce more. Make surpluses or shortages, whatever floats your boat, makes no difference to me. However consider, if you make surpluses and the price tanks to base price or just above for a product then corporations don't make a profits. At least that is my experience. I watched Market values tank several trillion from this like clockwork. Even tinkered with my CM contracts somewhat, to minimize it as best I could. Naturally I took notice, especially when old reliable shortages disappeared to significant surpluses. Consequently the profits became deficits, it was hard to miss. Production Plants are still in surplus while making deficits. Where are all the new corporations coming from? I have an odd interest in those.
Either way, you cannot just kick things to surplus and not tweak the price mechanisms in kind, that is a significant game changer for Enterprises seeking profits. There is another aspect to this, it takes to long to build a solid profitable corporation with a cushion to close it since you have to pay the Home Country a significant penalty... I don't like closing corporations. Though I would if I could depend on the surplus being there consistently and indefinitely.
If Price depends on shortages (one assumes supply and demand plays a part), then C3s have have to react quicker or the formula for the price has to be slower to adjust down or the swing from surplus to shortage and back should be seriously slower. The way it is now, you cannot close or build corporations with any assurances they will be profitable regardless of quality or remain profitable for long. Enterprises are not countries, operating corporations cost more for them. Well, unless you have tweaked things again or you want us to just build Services at this point, which I am seriously considering. I watched it with the Production plants. Price changed pretty quick depending on the Surplus or the Shortage. Bought a few to watch it since it was close to base, may continue if I figure the Price will ever go up to near where it was.
PLayers may understand and dump mass quantities into the markets, that is fine. Then just tell us this is what happened to Electric Power, Software, Hightech, and whatever else I may have missed. You didn't say that previously though. We all do not have access to that information. Had I, I would have kept my trap shut and soldiered on.
Personally, if I cannot get a product because of shortages, I build a corporation and supply it myself or get it from my Common Market if available. Services are a Prime example. Not one time have I complained about shortages, nor did I ever intend to. My Game is my Enterprise. Shortages are why I build my corporations. If cannot trust the markets to retain some bit of normalcy from one day to the next, why should I as an Enterprise build a new corporation? Unless you intend for us all to be in "build and pray" mode or want us all to just build Services, then honestly we shouldn't...
