Initially before publishing the mod there were supposed to be 2 new Senate positions - Princeps Senatus and Tribune of the Plebs. Both positions were cut before release because they sometimes caused crashes

Princeps Senatus would have been the highest position in the game, requiring having held the rank of Consul and this position would be held for 20 years. Irl it was a position outside the Cursus honorum but was highly influencial and depending on the moment in history came with pretty important privileges. The trait for the position would have given a greater chance for getting elected in the future as well as giving popularity with the senate.

Tribune of the Plebs was a position that I kinda questioned myself about because it is supposed to be held by a plebian but all the family members in the game ar patricians. The position would have had no requirements and elections for it would have been held yearly. The trait for it would have given popularity with the masses
