You have more faith in the courage of fdev to do that than me
Not wasting all the AX content and giving the AX fans something to do in this new future seems entirely reasonable. There's plenty of ways to set it up so that the only systems which get depopulated are the ones no-one really cared about anyway.
Seems more like a 'we're done with development - have fun' parting gesture (which is good - more player agency / less fdev oversight is probably the right direction)
Oh, they've been wanting things to need less manual intervention since maybe Powerplay v1 - and between Powerplay v2 and Colonisation, we might really be at the end of CGs - but I doubt this is the end of development just yet.
Whats the distance from Kamadhenu to Colonia's borders?
Asking for a friend.
Roughly 22000 LY. Assuming that you can colonise systems (or have people happen to colonise them for you) sufficiently rapidly, your absolute limit on speed is only being able to exploit systems in range of an existing Fortified/Stronghold system, and only being able to promote systems by one level a week, which gives you a 10LY/week pace should you be able to find an optimal straight-line route.
See you there in 50 years, I guess.
From the moment this is enabled, nobody needs or cares for a why other than "because I can."
Oh, of course, on the individual level, as is absolutely right. But Frontier has the wider game balance and 'ecosystem' to consider - a bubble of 80,000 systems is actively worse for many gameplay types than a bubble of 20,000 systems, for example.
All joking aside, I wonder on the viability of 'Colonising' a system purely with Odyssey's Settlements?
They've said that the first asset in a system needs to be an orbital station, I believe, but after that there's a lot more choice.
