I only played this mod for three hours as Caledor and I had so much fun and difficulty. This mod gives you a powerful faction but you are still faced with enough challenge to keep hold of your own lands. I even started playing this mod on medium difficulty. I'm gonna restart a new campaign on very hard difficulty today and I'm sure it'll last me a while before I get bored with Caledor, then I'll play as the Nagarythe next.
This mod is stable, I only had one crash to my desktop when I was facing a huge army of demons. This is understandable with so many heavily modded units on the screen, but this mod is supposedly a beta and yet it's outperforming any other beta mod or full release mods I've ever played. I like how the auxiliary traits look and I enjoy controlling the Phoenix King!!!
The only problem I have is with the diplomacy text. It's all colored white, so it's difficult to see. Wealth, strength, reliability, etc..
Playing this mod also got me interested in the novels.
