First thing i did? Demolished the temples to the pagan gods. Ofc, the population was displeased, specially cuz of culture, distance, and i assume lack of safe passage by land. I do not remember the town name (Olisipo? Would make sense), but after conquering it, i decided to ocupy.
I charged the ships towards the pillars of atlas and disembarked on current day Lisbon (first cuz i am Port myself, second cuz wanted to both kick the ass of a barbarian tribe and have a good invasion point for the Iberian Peninsula). I played as brutii and on a wacky decision, i filled 2 birremes (outdated at the time already) with troops and a general. I played recently, and when comes to cultural public order i tried something.
