I saw that in a game I started earlier but got distracted before I made it to the forums.  Started a soak and thought my custom faction was doing well, about turn 200 I noticed my faction had encountered the Krynn and Drengin so I checked out the power ratings.  My custom race had a bit over 300, the Drengin were a bit under and the Krynn had over 1200.  

I stopped the soak, dropped the fow and started looking for a why.  The Krynn still had pirate bases in their zoc and near their homeworld but they had taken most of the middle of the map.  I didn't see anything obvious that would explain why they were so overpowered.

In my gameplay I do find the Krynn very strong.

They have greater custom techs, good growth and morale, prolific is just badass when you expand fast. They don't really have any big weaknesses.

They also have Patriotic, which is a very good trait for large empires, and probably a fairly reasonable one even for small empires.

I have a suspicion that the computer either slows or stops expansion when its morale penalties get too large, but the Krynn don't need to concern themselves with this issue. Might be worth making a test game where a few custom factions which are almost identical to standard factions except for the substitution of Patriotic for one of their traits to see if the Patriotic trait really is a prime suspect for the cause of the power differential.

At the risk of repeating myself or sounding like a broken record the Krynn and the Thalen used to play like this in GC2 that's why I hardly ever played with them on because they were and looks like they still are over powered.

I imagine this isn't much of an issue on smaller maps, just the bigger ones. Tho I'm hesitate to Nerf the trait, is my fav one for the yor

I don't mind one trait being stronger an all the others.. Maybe its just me

Maybe just keep it as it is but make it only work for the first 10 planets, then have it scale up on the bigger maps.

So their race trait is making them go bananas? Because now they are extremely excessive while AI are being limited to expansion, malevolent AIs seem to adjust fine due to their moral bonus through ideology. 

It's interesting that we can make custom factions and actually play test them like this by having them play each other.

So the Krynn are now the dominant race. That's interesting. 

Prolific should not remove the approval penalty from expansion... just make the race being Prolific get HALF the penalty. This is still very strong but in no way OP.

I'll add one more to this thread.  Turn 150, insane map, Challenging.  I had to retire (first time ever).  I had 56 colonies and 45 ships.  Krynn had 121 colonies and 583 ships.  It's not just the expansion.  By itself, I could probably handle that.  It's the malevolent perk where every planet gets an overload class ship.  I had three AIs, all having taken that perk, declare war on me (I was basically surrounded).  Just one of their fleets more than tripled mine.  All three was just too much (even though my ships were better individually).  Because Malevolent races like to declare war on "weak" opponents, it almost forces a player to follow the Malevolent track, at least until getting that perk. It also forces pursuing military tech.  I'm not sure how someone truly follows a Benevolent path as the game plays right now.

Yeah the balance is broken on much higher map types, I just cloned them and replaced Patriotic with another attribute, it stopped them from going crazy and brought them back into line with everyone else.  

ah Patrioc. I'll take a look at that trait.

To be honest I'm actually fine with the notion that having a large number of planets on bigger maps will get very hard after a while. If we might get to have 100-200 planets but more is impossible I'm fine with that. I see no reason why populating half or more of an insane map should be needed.

In smaller maps the penalty should perhaps be increased a bit to balance it.

Both of those victory conditions should still possible. Conquest are certainly possible and influence will require some serious effort into approval to pull off.
