I found this extreamly game breaking. An event comes where Portuguese traiding company demands your city. I dont know if AI is smart enough to press no-option but it will only delay inventiable. Your civilization will be annihilated Portuguese stack of doom.
I assume you're playing Kongo? If the Portuguese trading company conquerors get there soon after you've spawned, (which shouldn't be happening too often) then you're screwed. However, you should have enough time to build up and expand so you can actually fight them off.
