Passive influence drain (destroy factions permanently)
Very same principle as the mod Destroy Factions Permanently (passive influence drain) by Reman but a little more strongly. I added a passive drain of -1.5 influence (per day). Hard start but manageable and also allows to destroy factions more in early game. Tested on version 0.4.90. You can not add it in your existing game (well, you can, but it will not take effect).
