I dislike the companions in Bannerlord. They only seem to come in four personalities: Spurned Scholar, Woman Sticking It To The Man, Super Grimdark Edgy Murder Boi, and Too Good For This World Goody Two Shoes Hero Guy. I know, it doesn't matter much once they're in your party, so it's not like it takes away from the game. It's just bothersome when you see a new nickname in the tavern and it turns out it's just I Loot And Murder And Paint Myself In Blood Of Infants I've Killed While Jacking Off Because That's How We Do In The Dark Ages Angry Man #7.
The only one I'm fond of is the capitalist healer from Sturgia who basically said "fuck all this helping people in need and war and shit, I'm gonna go make money". Well, I like the Tragic Scholar types too, but I'm just leant toward that stereotype, so it doesn't count.
But on to actual mechanics, now that ice gotten the rant out of me: It seems you don't get all companions during the same playthrough any more, which is a shame, but since there's so many of them, I guess it makes sense. But does anyone know if they eventually start spawning more of them after a while? I spent all my last play through looking for a trader companion (I've only seen one before, the Azerai trader woman -- there was one Cartwheeler once that I guess could have been a trader but seemed more geared towards engineering, didn't look at their stats) but couldn't find anyone. I hope it was just bad luck and it's not the case that you can end up having say only combat focused companions available because no other types spawned when you started.
Also with all the thievy types abounding everywhere. I look forward to seeing the crime boss stuff be implemented. I suppose they might be for planting a boss of your own in cities?
