Buy-able only items?
I feel like the Store is going to get old pretty soon for some reason. Like, why would I buy stuff if I can make/get it myself? (this is just me, I guess some people will find buying ships and items very handy maybe.
So, why not adding items that can only be obtained in the Store?
Special Hand Grinder (or whatever name): it will be like a normal Grinder but it will not destroy items when you grind a container, also it will not destroy the Power Cells.
High End Hand Drill: Detection Range 100 meters or more, Auto Ore Collection, faster drilling, etc.
Rare materials, ore: Platinum, Uranium for example. or maybe, Aluminum, Titanium, Copper, etc
Also, should be weapons and ammo only buy-able items too?
