This mod aims on making the sandbox mode more entertaining. It changes, tweaks and adds some units and upgrades. It should be fully compatible with vanilla (no DLCs, no Mods, no Tweaks needed), but the changes might imbalance the campaign game (making it either too easy or difficult).
The Druid Grove was another modding example which is used in this mod. It gives the Britons and Gauls a cheap moral boost. Several buildings have become cheaper and some have become more useful.
