I agree with everything here, and I'll say I've united Italy as Two Sicilies before, but it's just asinine how hard they make it. You literally have to research every diplomatic influence tech to even get a change, i.e. divert your entire tech path from whatever you were previously doing to that. That's why I never play as Two Sicilies anymore, even though, in theory, it should be a fun nation to play as. Vicky is (for better or for worse) really imba. The time frame is also really short, so having to do the previously mentioned tech diversion kills you more than it would in any other Pdox game.
