I did a small update. Small but enough to affect the gameplay.
First: The briefing it's more detailed. Now tells to the player how to be able to train Fremen and Sardaukar, the new requirement for the Starport...
Second: Now the starport stock units twice as fast; this means that after doing a 5 combat tanks order, the player only need to waits a couple of minutes to be able to order 3-4 more. It's suggested to buy units with a discount to save some money for future orders.
The AI it's affected too, so he will send more units into attacks too, making this map harder (but not too much, the AI still will split their units when attacking). Overall the player can continue to buy stuff regularly.
In fact; during my final play; I manage to destroy all the enemies present on the game (except some Tleilaxu turrets) which took me 1 hour of gameplay.
I updated the first post to add a few more TibEd edits.
Anybody creating an Ix or an Emperor campaign would notice some problems with those Houses. As Ix, deploying a MCV the game crash, and as the Emperor the player can't build his own Imperial Palace.
Changing that it's very easy, but requires an external program (TibEd) plus have some experience with the tool. For that reason I decided to add those editions already done to make it easier for everyone.
There are a couple more, like making the tanks to no be able to crush foot units or including the only practice type of units (grenadier, Stealth Raider...); check the first post for more info.
