The Protectors of Etheria is a stand-alone mod of the game Warlords Battlecry 3 (i.e. it can be run without having the original game installed - 100% free full game). It is an improved RTS/RPG game with new campaigns, quests, terrain, units, items, heroes, modding features and more. Beta versions available for download!
Lot's of fun!
You can create great scripted maps, using nis files and the manual provided (you can change teams, ai dificulty, learn researches, make traps, change terrain, remove/add features - with sounds and animations - give/remove units/buildings, special victory events - like killing a titan - and more related to campaign like create your own custom companions and mercenaries)!
All you need is notepad, the provided Manual and ideas/time. Thank you Patrick.
That's awesome. Reason I love Paradox games is exactly that. Able to tinker at my leisure.
