Hi all, 

I tend to like long games with smaller fleets, longer building times etc. also slowing down colonization tech ramping.  

I've already found the research and tweaked it to further slow down tech ramping in [Research].xml and tweaking [TechnologyScienceAndExploration].xml 

What i'm having a challenge decyphering is finding out where cost/values for ship building and maintenance costs are.  

after this I'll probably start looking into defense/weapons etc.. to tweak them. 

Thanks in advance for any light you can help shed.

I believe that base ship costs are set by hull in "Public\Simulation\Battles\HullDefinitions[Balancing].xml"

Not sure about maintenance costs

Good find thanks CyRob.  Also found the module slots as well.  looks like the "SystemProduction" value.
