Armour Astir Advent is a gundam and escaflowne inspired ttrpg set during a conflict between the fascist Authority, and the rebellion. and that's all you need to know about the setting, any further details are chosen by the players, it's in essence a mech game like lancer, but trying to emulate the felling of shows like Gundam, which focus more on faction fighting and the psychological toll of war. One of the best praises I can give it is that the Gravity Clock is the sickest relationship system done in any game
