There are a lot of great things about this mod but I have to dis-recommend it for long games. Your base will get destroyed by artillery, particularly if you have other mods installed that add military options which will be used by the Castra enemies. In particular, the enemies will research and build artillery, and their increasing range upgrades will make it impossible to passively defend your base. In order to keep it going you will need to devote a lot of attention to actively attacking the enemies. The health of the enemy bases also becomes somewhat ridiculous. I'm only at 88% evolution but they have 148k HP.

It's especially bad if you have a mod that adds nuclear artillery, because the Castra artillery will research and use it. I can't even tell what direction the shells are coming from so I can destroy them re-actively and they out-range my radar coverage.
