Ludus Magnus Studio is showing off the Horologium, a major portion of the mechanics for Nova Aetas.
From the preview:
The main aspect of Nova Aetas is the flowing of time.
Every action made by the characters, every decision taken will be marked by temporal flow.
Each move has an amount of time used to carry it out, every movement is measured in terms of time.
Thanks to an original and intuitive round management system Nova Aetas will offer a new, different gaming experience from what has been introduced so far on the board games.
