Expansions: BGS Guide Best Current Thinking

  • Where to: The following sequence is followed-
    • Normal Expansion - systems which have less than seven factions present, no previous retreats. Closest system within priority is chosen.
    • Second chance expansion - systems which have less than seven factions present, previously retreated. Closest system within priority is chosen.
    • Invasion - systems that have exactly seven factions present, including a non-native target faction not currently in conflict. The system with the lowest influence target faction at the moment the expansion complete is chosen (the effect of previous retreats is uncertain).
    • Long-range Expansion The expansion completes but there is no relocation. The next expansion has extended range. If this expansion already had extended range and still couldn't find a valid target, then this system will not generate any expansions at all for a while.

Is the expansion priority as stated on Page 1 correct ?

In all of our 80+ expansions, until last night we had NEVER had an Invasion happen without have a failed previous expansion AND having run out of long range expansions (i.e. Invasion was the very last option)

Last nights expansion was only 17.5ly but not after a fail (our last fail was never "used" but it was elsewhere many months/expansions ago), and there were still 3 systems within long range

It has held with us up to this point - we have [very] many invasions before long-range. Will keep an eye on it.

Thanks for the confirmatiom. I think what I am seeing matches what you state !
Its just the 1st time we have ever seen it work like that (out of 80 expansions, we have only invaded once or twice, and they were a long time ago)

..off to do some bug-fixing :)
 
Invasion before long-range has certainly been the consistent rule I've seen.

Prior to 3.3 the necessary conditions to invade were rarely met, so long-range expansions were certainly more common than invasions then, even though they were lower priority.
 
Hi, I have a question about long range expansions. We triggered the usual pending state on the 2nd September and then went into Expansion as expected. The faction is already in all populated systems within a 20 LY cube so we were expecting a long range expansion to trigger. There is a system within the 30 LY cube that has 5 factions - XYZ distances are 14/24/18 LY and I was expecting that to be the target. However, the first expansion period ended today and we are no longer in an expansion state. The local news in our source system says that we have expanded, but we are not in any new systems. Did we need to fulfil some extra condition to trigger the long range expansion, e.g. being over 75% inf when the first normal-range expansion stage finished?

Long range expansions take 2 expansion cycles. The first one doesn't go anywhere, but now the 2nd time you try to expand it will have the extended range. Be careful not to expand from the wrong system now, as that would still consume the long range expansion.
 
If you have no valid expansion target within 25ly the expansion will fail and you should enter an investment state.

I thought that a second expansion round with an extended search range was possible based on a larger cube with 60LY sides aligned to the galactic map axes and centered on the expansion system, so sides 30LY in each direction from the expansion system? I took this from post 184 by Ian Doncaster in this thread:

Yes - this is still correct. 40LY side standard cube, 60LY side extended cube.
 
I assure you expansion at base is 25ly max from the expanding system because my PMF this year had a 23.66ly & 23.97ly expansion with no boost from a failed expansion.

In which direction? You can get a 34 LY expansion if it's in exactly the right direction (I've seen as high as 29 in practice), and fail to get a 21 LY expansion if it's in exactly the wrong direction - the expansion selection region is a cube, not a sphere.

This also means that you can go to a further away system, apparently skipping a closer one, because the more distant one is inside the cube (on a diagonal) and the closer one is outside it (towards a face)

Example here:
The faction starts off in Ravenhold.
Its first expansion is to Tir (21.89 LY)
Its next expansion is to Chrysus (26.81 LY but still within the cube ... skipping four closer inhabited systems outside the cube)
Only after that - and requiring extended range from a failed expansion attempt in March - does it expand to Kajuku (24.72 LY)
 
My understanding was it's not a cube or sphere it's a direct line from the expanding system but your example has enlightened me so thank you.
 
Thanks everyone for the info above on long range expansions. Our next system to hit 75% info just completed its expansion cycle and we have arrived in the expected system. Just to confirm some of the advice, even though the source system was not the same as our previous system which had the (targetless) short range expansion, it still went straight to long range. It was near enough to the original that the long range choices were the same systems. Thanks again.
 
Seems that Invasion of a Controlling Faction is not possible any more :(
We had one due tomorrow (Only Non Native Factions not in Conflict were Controlling Factions), but the expansion happened 1 day early and was a failed Expansion.

Last time we were in a position to try it, it coincided with FC Drop Day, so disregarded the failure, but this time there is no excuse.
 
Basic questions here.
How long do expansion and Retreat states last?
Are they both prevented if the levels are too high and low on the last day only?
Cheers
 
Expansion is about 10 days (+/-1) from Pending to Completion. Once it is Pending, you cant stop it. The destination is determined on Completion, so in certain circumstances you have some control.

Retreat is 5 days (?ish) - Determined on the last day being above or below 2.5%
