I'm having a tinker with the Bias files.
My current idea is to increase positive and negative biases (without going overboard) with the races split into 4 groups (ensuring each group uses a variety of weapons).
By increasing the positive biases for races within a group they are more likely to form Mutual Defence Pacts. With the changes to fleet coordination in Universe this should mean more mega fleet battles.
Each group has negative biases set against another group, so they are more likely to go to war i.e. Group 1 v Group 2, Group 3 v Group 4. I've had to many games in the past where nobody declared war even on Chaos throughout the entire game. So now, if you decide to take a back seat and your partners go down, you could then be facing a strong alliance of opponents, without as much support ...
I approve that.
An idea: I think reducing war wearness for each race would be more benefical for the AI.
The best would be normal war wearness for the player and maybe -50% to -75% or 100%(no war wearness at all) for AI. But I dont think there is a way to achieve this easily without going in the race file, for each new game (change your last game race for the new setting and change back to normal setting the one you use in the new game.)
Would be easier for the AI to be in war for a long periode without hurting aproval, economy, etc.
What do you think?
Will help testing your change soon, because I am realy interested to help improving the AI. (Did not play since 3 week)
