I've actually never found it... granted I only looked for it half-heartedly. I think they'd be much easier to balance with flat prices. 

Great! 

Do you know it is save compatible to my current 8.1b save game? 

That's not necessarily a GRM thing...

GRM doesn't touch what AI can or can't do. 

Also be aware you can get mercs through events and ideology and these are sometimes T2 mercs. 

Ah Thank you! That's quite handy! Next version maybe I'll go with flat costs... my hope was to reduce credit cost but increase rare/unique resource cost anyhow.

That's also informative about the GRM-Ideology... I'l have to take a look at that, and see if it crashes people who don't have the Mercenaries expansion.

Thank you!

A few notes for those that don't have the mercenaries expansion.

I get an error message for The Nyryloth Resurgency faction: Unknown ship style.

The ship classes like : Unit transport, command ship... are using Human designs.

I have modded the following files to remove mercenaries:

CultureTraitDefs:
    GRM-Independent-02: remove <ValueParam>5</ValueParam> (this seems like a bug)
    GRM-Independent-03:

AwardRandomMercenaryShip -> AwardShipOfClass,

MercenaryTier1 -> AwardGunboatBlueprint,

MercenaryTier2 -> AwardFrigateBlueprint

1-GRM Event Stranded Merc:
    GRM-Stranded Merc-01:  AwardRandomMercenaryShip -> AwardShipOfClass,

MercenaryTier1 -> AwardGunboatBlueprint

I have found a bug with the Outbreak event:

IdeologicalGalacticEventDefs.xml:
    Set lines to Colony instead of Planet     (lines 976 and 1062)

Btw figured out how to replace the "project" model for various missions.

I haven't used this mod in a long time because you change some of the same xml files that I change for my personal mods.  I decided to check the 8.5 version and found that there is very little overlap in xml files that are changed.  As I looked through the files we both use, I thought I found an error.  I installed the mod and used it without any others and found that I was right about the error.

In the GRM 8.5\For Your My Games - GalCiv 3 Crusade Directory\Mods\GRM\Game directory, the FactionDefs.xml file has the pirates using GRM L (33).png as their logo.  This file doesn't exist anywhere in your mod.  When the pirates appear in the game, they don't have a logo.  I found this missing file  in an earlier version (5.0) of your mod and put it in the correct directory.  When I restarted GC3 and loaded a save, the logo appeared.

I also checked 1-GRM Minor Pirates.xml in the same directory and found that it refers to GRM L (35).png for both pirates.  That file also doesn't exist in the current mod but does in the old mod.

The only other problem I have had is adjusting to the changes you have made.  This is my problem, not yours, so I'm going to keep playing with your mod for a while.  Keep up the good work.

Hey there. That won't affect play or cause crashes.

Thanks for pointing out the bug! I changed logo names a few versions ago and totally forgot about that for pirates and the minor races.

Updated for next version.

Meanwhile progress continues on the Nyryloth set. Kinetic and Missile weaponry developed, as well as a Drone Dock.

Interestingly enough, it doesn't. I thought it would, because I had a random crash sometime during my first GRM session and chalked it up to another empire picking the mercenary trait. However, I accidentally wound up playing a game with the mercenary files intact - I thought that GC3 would hotload the modified files, and didn't want to restart the game again - and stumbled upon a mercenary stranded on a planet.

Since I figured the game would soon go up in flames anyway, I chose to rescue the merc, and got a Mjolnir's Fury out of it. (I later got a Guardian's whatsit and a Nomad out of the ideology trait.)

I suspect that it might have crashed if there weren't any mercenaries defined in the game files, but since GRM has its own mercenaries, the game just picked a random GRM merc and went with it.

Well, I doubt you can enable the Bazaar in any form or fashion, so people can't properly buy mercenaries. You also can't (feasibly) add the vanilla mercs to the mod. Your custom mercs are only available at random, from a very limited selection of sources - I don't think it's all that bad.

The logo files for the minors seems to be missing...

GRM L (23).png for the HuronImperium for example.

Note: i have found the files in your old version 5.0!

I know that some like to play with very big map, but i prefer to play on Huge map (with around 50 to 60 planets).

With this setup i find that the ColonyLimit from governments is too high. For my next game i will try lowering all the values by 33%...

Note: There are no governments with a ColonyLimit of 10-12. I would set Utopian and GRM-Gov-PostModernClans to 12.
