If these were already suggested, please delete this.
My ideas are:
1. Creation of planets in some systems, that can be used as factories to produce goods that can be sold in the market.
2. Allowing the player to build space station modules for production. The trick is- planets are not created by a player, but can be taken over, and can't be destroyed. Space station modules are built by player but can be destroyed.
3. You will need to purchase raw materials to produce things, so it will increase market use.
4. Actually, there can be CHOAM's trade outposts in the galaxy, that will be selling the materials.
5. You will be able to use some of these products yourself, such as missiles. For example:
Production of the Ultimate Weapon (tm)- when used on a commander/ event, it reduces the HP of the fleets by 90%. You have to be level ,oh, let's say, 100, to produce The Ultimate Weapon. Or D-day firecracker
. You wouldn't sell that, would you? As I said for example.........
6. Construction of research facilities, that lower the cost of researches.
7. Creation of warp gates between some systems. Player that controlls 1 can choose the system he wants to open portals to. Could help greatly in the system invasion.
Ok, I'm done. Cheers, AFB.
