Nova Aetas is set in the world of Calradia, but in a later period. The Old Medieval World is vanishing. A new era is coming and you, the player, will experience this. Nova Aetas is Latin for A New Era. The main targets are realism & extended gameplay.
This mod has a great concept and awesome new mechanics, the only reason why I'm not giving it a ten is because, at times it can be unplayable. Crashes, errors, and minor bugs plague this mod. If you can play this mod 15 minutes straight without crashing to your desktop than it's only by pure dumb luck.
