Adding Some Difficulty

[zastava128]

I have a rule to never use Z-fire against the AI.

Somewhat similar to using low quality troops - try playing an underdog, like one of the minor Axis nations (and refrain from overloading on German equipment!). Taking on the Soviets using Hungarian tanks is a very different story than using German panzers...

Good one!
As the AI will never z-fire.
I may use it once or twice in battle myself,(to discover hidden units that fires on me) but not excessively.

Here's one,don't bulk up on artillery,keep it comparable(say 5-10%) to the force value you have.
