Is "Royalty" an overpowered leader trait? All cities grow 2x as fast?

I don't think it's working as intended. The tooltip for the ability says it's supposed to give +1 to prestige, but the city info page says it's giving +100%. Doubling your prestige is certainly very very good and may indeed be overpowered.

I always take it.  It provides truly explosive growth in the beginning, and every 4x fan knows how exponential early growth becomes.

In my current game, I have 2 champions with that trait and I don't notice an increase.  I thought that maybe each provided a +10% bonus so I had not reached a noticable improvement.  Are champions' bonuses weaker then a sovs?  (Well except the +1 gilder....)

It's probably overpowered, but not by much considering how unimportant population growth is.  This isn't a standard 4x game; more population doesn't equal more production in either linear or exponential forms.

I don't think Champions with the ability are working.

Population is still bloody important. Maximizing production is best achieved by making upgraded cities with the high-level improvements around the right resources.

The population growth is useless, yes, but it allows you to reach those cumulative +20, +30, +40, and +50% increases  twice as fast.  I think it only works with sovereigns right now though.

It might be overpowered but it's working as intended. It does double your growth which certainly helps. However, to only add a +1 prestige would REALLY nerf this ability to being useless. Also, NPCs with Royalty essentially have no bonuses because they don't add to the bonus.

All the histories need a little love and buffing to make them more interesting, imo.

Yup i second that. My Royalty Champion does not provide the bonus as reflected. In fact she's not the only one. I got another production +10% guy, but apparently, he broke too. Whereas my farmer is providing +20% food prodcution nicely. Could be a bug randomly dorking it up for us.

I would definitely like to see the other backgrounds buffed, instead of this nerfed.

I mean... 2 crappy sentinel units or a chance to ACTUALLY build level 5 cities in a game? I know what I choose.

Royalty is only functional if you imbue them, i think. or marry them and have the trait passed to your children. Otherwise it only works right on your sovereign.
