I have to agree with Wendy.
Six months ago I was at level 14, valiantly striving for level 15 and only one FI point off it, expecting not only to make it in a few weeks, but to stay there. Over half my countries were fully garrisoned and three of them were war slaves with serious offensive weaponry.
Whatever the GMs have done since then, now I am back down at level 12, struggling to stay there, and all because of my falling FI. I have turned one of my war slaves into an econ country, raised my war level so that I could sell / destroy weapons in 80% of my countries and used the workforce in all of them to build more corps, but still my FI falls. No weapons, 100% private corps (most of the owned by me so they have good salaries and they are good, mature corps) 80M+ population and the countries are still struggling to hit 130 FI. Some of them are only just above 100 and still falling!
It's incredibly depressing to log on day after day, build another corp, balance workers, think up every strategy you can to improve finance, and see the graph still steadily going down. I've been playing for 6 years but I've never seen this before. I don't pretend to understand this game so well that I can tell the GMs why. All I know is that it's happening, and nothing I can do seems to make any difference.
As Wendy says, it's the people that keep me playing. But for how much longer? I have no idea ...
Hugs and respect
