@Blackpaw: The reason I only build 1 level of fort is simply because you don't need more as long as you have it manned by 2 infantry divisions at all times.
Contrary to HOI2, you no longer see the final date of a serial run. only the completion date of the current one is shown. After that one is finished, the AI will calculate how much practical you gained and base time and cost for the next one on this. As a consequence, Serial runs are no longer the be all and end all. It is now more cost-efficient to start a new run every time the last one is finished. That doesn't mean I won't use them. mainly, if there are "small" things, such as trooptransports or convoys/esorts, that you could forget, use serial runs to keep them going.
adding more levels to your forts does make them harder to breach. But with all the stuff we'll need, we can't afford to spend 2 years on them.
Another thing I would advice everyone who's reading this, is to try not thinking in HOI2 terms. HOI3, especially with the addition of Semper Fi and For The Motherland, is a different game. The artillery brigade, for instance, no longer slows infantry down, like it did in HOI2. It is now a force multiplier. I will explain in more detail later, but for now, simply put, each combat takes up a certain amount of space on the battlefield. Support brigades do not. So they allow you to squeeze in more firepower in the same amount of space. When we get to the good stuff, I will be spending quite some time at explaining the OOB of your army and how combat works. It is quite a different mechanic under the hood.
