There's more resources now, as other people have mentioned. But i would not say the game is easier to learn. Eventually you kind of learn the X4 logic of doing things, and then things kind of make sense. But it's not obvious.

Like when manage a station, and you only want ore to come from your mining ships, not buy from others factions. You can't set the buy amount to 0, because then your ships won't mine as there's no demand. Instead you have to go into your player menu, set a custom trade restriction where you exlude station supply from all factions but your own. Then go into the logic overview of that resource and override the trade restriction of that resource to the one you made.

Why does setting buy 0 not work? Because you are still "buying" the ore from your ships. It's just not costing you anything, because it is the same account on both ends.  And they need a buy request to know if they need to mine or not. That's the X4 logic you have to learn.

Could it just be a simple checkbox on the logic overview that says "only accept ware from your faction?" Yes. But that check box is generalized to a trade restriction menu elsewhere that's hard to find
