This may be a controversial or unpopular opinion, but I really think the barrier to entry for Colonisation has been set far too low. 25 really is pocket change to claim a system. And we make a profit hauling the commodities required. Personally I think taking on a full system should be a substantial commitment and the claim price should be more like 500 mill.
Apologies to the newer commanders that this would effect, but I'm not sure it makes sense for commanders just out of flight school to be a able to take on managing a system and building stations. It should be a goal you should want to work towards as you build your rep and wealth in the galaxy.
The current expansion has been crazy. Within a week commanders colonised 8000 systems and built 15,000 stations. A check on Elite wiki tells us that before now the full bubble was 20,000 systems and 66,000 stations. That means that within about a month we will have doubled it's size. The current bubble took like 1000 years to build! The current pace is both game breaking and lore breaking and just doesn't make sense.
Having system claims actually cost a substantial amount of credits will also give us something to spend our fortunes on. Most commanders are billionaires with nothing but an FC to really use them for after you reach a certain point in the game.
I think currently it's just too easy to claim systems and build stations. It really should be an expensive endeavour that requires thought on where to lay the claims. Not just have commanders claim everything in sight because they can.
It actually would be kind of expensive but they give you a refund when you hand your materials into the colony structure being developed lol
Before they made it any more expensive however I would think that they need to first be more profitable. My first paycheck was only like 4,400 credits. I think, for having had a tier 3 Coriolis, and having just completed my agricultural settlement, it should have been more profitable based on the starport alone. Since then, I've built three other settlements. I'm not expecting the paycheck to be much more than 50K, which is laughable compared to fleet carrier maintenance costs. I was hoping for an income that would help offset that.
If they work on the income aspect, they can help make settling the single system a little bit more of an evolved and detailed process. They could do this by making it so that you first have to build tier 1 settlements then wait for the returns in order to save up for tier 2 settlements. Once you've constructed tier two settlements you wait for those settlements to generate their income put those credits towards upgrading them to tier 3 status etc.
