looking to mod oligarchy corp links

That one is data, not hardcoded. It lives in Data/Gameplay/GlobalDefs.xml, in the OligarchyCorporation blocks.

There are three of them, Corp_Research, Corp_Influence and Corp_Manufacturing, and each has its own BaseTransferRate sitting at 0.06. Raise that to 0.10 or 0.15 and the per link share moves with it.

One thing to know before you settle on 0.15: LeveragedBuyoutTransferRate in the same block is already 0.15, so a normal link would then pay the same rate as a buyout. The buyout would still differ in that the host world gets no reciprocal share from you.

Before you change 0.06, work out what you are actually pricing. On the rates as Haalee set them out, the number that decides anything is not the link rate on its own. It is the link rate against the 0.15 a buyout pays.

At 0.06, a buyout is worth two and a half links.

At 0.10, it is worth one and a half.

At 0.15, it is worth exactly one, and the only thing left between them is the reciprocal share the host does not get.

So going to 0.15 does not make corporations two and a half times better. It takes a decision out of the game and leaves a formality in its place, and you would be doing that to fix a number that felt small.

Mine would go to 0.10 and stay there for a full game before I touched it again. The buyout stays clearly better, the difference is big enough to feel within a turn or two, and if 0.10 still reads as too low by the end of it then the problem is not the rate and raising it further will not find it.

I set on 0.10 and buyout on 0,20 not that big diffrence but buff oligarchy needed

Two links to a buyout at those numbers, so you have kept more of the gap than my suggestion did. That is a better pair than mine and I will say so.

0.06 and 0.15 shipped is two and a half.

0.10 and 0.15, which is what I argued for, is one and a half.

0.10 and 0.20 is two.

The difference between your change and mine is what each of us was fixing. I was pricing one link against one buyout and trying not to flatten the choice between them. You are raising the whole government, which is the honest fix if your complaint is that oligarchy is behind rather than that the link number looks small.

The part I would keep an eye on is the buyout. Going by Dev Journal 118 it is permanent and costs you a Corp Link slot for good, and at 0.20 that slot is paying you a third again more than it did. Every time that number goes up the decision to spend a slot gets easier, and easy decisions are what I was trying to protect against when I said hold at 0.10.

What would settle it after a full game is whether you ran out of slots or ran out of worlds worth buying out. If it is slots, 0.20 is doing the work you wanted. If it is worlds, the rate was never the constraint and no number you pick will be.

well I made balance myself:

changed godmachine buffs to: 50% research, 50% production, +100 flat money, 20% capacity, +10 movement, 1000% research for example was too ridiculas or 500% capacity  or whatever funny number was there

changed oligarchy links to this I said, changed free starting products from 0 to 3, made products mature faster a bit

empire is good enough no needs changes

and ... what the point of federation if empire is better version of it?
