Please don't think I ask this lightly...but...is it possible to manually edit the tension levels for a particular save?
I'm playing Japan, at war with the USA and have ground out the significant lead seen below, of which I'm pretty proud. It's been a long and hard-fought war. Now I find I'm having to throw every battle in order to keep GB from joining in and wiping the slate clean, which does not feel fun.
I know this mechanic has been discussed before, and I'm normally fine with it...but in this case it just makes the last few weeks of play feel pointless and I'd appreciate knowing if it was possible to give myself a pass, just this once...
On a side note, I'm in this position because of the frequent sinkings of large passenger liners by my (brand new, only entering service an in-game year ago, in 1938) submarine fleet. In 'unrestricted' I could understand it, and I appreciate that 'fleet support' is the safe setting, but it just doesn't ring true that every couple of months my submarine skippers trigger yet another major international incident when following prize rules (which includes the checking of vessel identity, I thought...)
Yes, it is possible to edit the tensions. Go to the Save directory, go into the folder for the save game you want, and open RTWGame#.bcs with a text editor, then look for the Tensions= lines - there will be one for each nation block, and it defines the tensions between that nation and the player nation.
