Increasing Campaign Difficulty

[TheConfessor]

Hi,

I am looking to increase the difficulty of the Tiberian Sun Campaign, so that I am constantly being attacked by tonnes of units, and the AI is constantly emptying its coffers and creating units. As we all know, the Tiberian Sun AI is pretty pathetic, and the campaign is effectively just an act of steamrolling the enemy off the map with very little in the way of "on field combat", so to speak.

I intend to play on what is considered "Normal" difficulty, so that I don't have deal with the 20% armor buff that the AI gets, which is a poor way of adding difficulty in my opinion.

In my Rules.ini, I have updated the following lines of code, and it seems at present that it has had no effect, judging by the behaviour of the AI in GDI mission 2, where you have to destroy the sam sites and the nod base. I don't receive any attacks after provoking the base and waiting 2 minutes.

TeamDelays=40,400,500 (I also had the 400 value at 9000, but it made no difference - the same behaviour was observed)
AIHateDelays=200,200,200

AIAlternateProductionCreditCutoff=100

MinimumAIDefensiveTeams=4,8,2
MaximumAIDefensiveTeams=6,10,4 
TotalAITeamCap=900,900,800 

Does anyone know if I am making the correct changes to get the result I want? Is it just the GDI level 2 that has some script associated to it that means the AI doesn't attack?

I'd also be open to knowing if there is an existing Rules.ini that I can use / refer to to make the campaign more difficult.

If it matters, I am using the Tiberian Sun Client found here:
