Scripting

• NTW has a comprehensive scripting language, but requires a decent knowledge of Lua to mod successfully. It doesn't contain most functions seen in RTW/M2TW (such as spawn), but offers many workarounds.

Text

• All in-game text is editable - units, buildings, tooltips, characters, settlements, UI text etc

Morale effects, fatigue effects, general "rules"

• In-game rules are editable. These includes projectile misfire rates, naval projectile incendiary rates, the effect that firing drills have on reload rates etc.

Campaign AI

Campaign AI is fairly moddable. It appears that all variables influencing CAI behaviuor are exposed, and moddable, but you can't change the algorithms behind AI decision-making.
