I love the supply and demand system. I preferred it more in EU3 where there could be a greater swing in demand, but I still like it.
I'll be keen to see if this new system is more or less enjoyable.
I like the concept, the idea of it, but the way that PDS don't share how it properly works is kind of bad, I hope that it still exists as a hidden mechanic in the new patch and that the events are based in this hidden mechanic, if the events are purely random it will be a great loss to the game.
