This might be a more historically accurate Akkad than mine. I really want a civ with a strong slavery focus though. I've seen a couple mods try to make slaver civs but they were quite awkward. Maybe I will draft Rome with an alternate leader and uniques...
Edit: So I decided to make a Roman republic
Roman Republic
Leader: Julius Caesar
UA: "veni, vidi, vici" ("I came, I saw, I conquered")
Begin with the honor tree unlocked.
No occupied unhappiness or resistance from conquered cities whose founders have researched less technologies or have less social policies than Rome.
UU: Slave (new civilian unit)
-Workers and settlers captured by rome automatically become slaves.
-half gold maintainance of workers.
-improve tiles 25% faster than workers.
-when stationed in a city, a slave can be sacrificed for a production boost.
UB: Amphitheatrum (replaces colosseum)
+1 culture unlike colosseum it replaces.
additional +1 culture, +1 tourism, +2 gold after flight is researched (so total output is 2 happiness, 2 culture, 1 tourism, 1 gold.)
