Ah, EOS. Gave it a shot. Water seemed to take an age to produce compared to other similarly valued items. Tried the balanced approach, failed miserably because having a fully stocked store is like shooting yourself in the foot. I want to like it, but it's deeply flawed. The only way to turn good profit is to pick and sell one higher priced item. I remember making bank by selling airplanes and skyrocketing above everyone else.
If things were balanced to all be about the same profit no matter the price then it would be fun - market conditions like competition and availability of suppliers would dictate what was best. But with such a deeply flawed demand model, only the most expensive items will ever be worthwhile.
The game is flawed, yeah. Price caps are making it even more flawed. It's not really worth putting lots of thought and time into it, but it's still kind of an interesting diversion.
This is the fun part of the game, though -- when everyone is too poor to make everything they need themselves and must buy components from the BtB. Later, when everyone is super rich and makes all components they need, it gets old fast.
I remember how aircraft, boats, and cars were the way to go in the old game. If you had the money, you wanted to get into those industries. But it required a very high investment to get into those industries. You pretty much had to be already rich to get even more rich in those industries. The quest system that gave everyone gazillions was not exactly helping the situation.
One reason turkeys are so profitable in this version is because they take a lot of earlier tier products to make. Products that require lots of components should be more profitable than early tier products; otherwise, what would be the point of getting into late tier products? The problem where it is currently more profitable to sell just turkeys and nothing else should eventually go away as more products that are similarly profitable become available.
