Lord Mndz,
To a limited extent, that already happens. With High Education countries focusing on products that use a lot of High Tech workers, and low education countries focusing on mass employment Corporations. Pushing the difference too high would would risk unbalancing the game, and require players to get unreasonably high/low education indexes.
High level Corps are already quite profitable, based on their base values. The larger differences in profits are caused by market situations. So if a high level product is being over produced, it's going to lose money, and if a low level product has a severe shortage, it's going to make money. That's a good thing, as it makes players balance the market, instead of just spamming whichever Corp has the highest level.
If you look that the employment levels for different corps, you'll find they already vary a lot. With some using x10 as many High Tech Executives as others.
Daniel,
I think you missed the point, having bigger diversity is attractive as you move from one type of corporations to another ones together with your economy as it grows. Also if you look at types of corporations players build today you will probably see maximum 10% of all types that are being build and rest 90% types are almost never being build, the bigger diversity in hiring and net profits would solve this situation. There is no risk to the balance at all, while enabling players so think and search and create strategies of development is what I understand as attractive from player perspective.
Today I build the same corporations I had been building 10 years ago and that is the fact.
Also can someone please explain to me why corporations in C3 countries also upgrading quality and efficiency? I think demo contries with demo corporations should not be upgraded but maybe there is some argument to explain it.
