I rather suspect that the Korx were generally willing to trade with anyone they could; it's their ethics and/or morals that placed them into the evil category, not their trading partners. They're described as being willing to do just about anything for money, which strikes me as more 'evil' than 'neutral' on the ethics and morality scale, and I can't recall there being anything in their description indicating that they would prefer a certain set of clientele based on common alignment. Granted, being 'evil' probably isn't the best way to make trading partners, but their kind of evil always struck me as the "there is nothing I won't do for the right price" kind of evil rather than the Drengin "torture and kill for sport" kind of evil or the Yor "wipe out all life in the galaxy" kind of evil.

The Korx to me were the expression of what an amoral race is.  Neutrality isn't the same thing as amorality. People who are neutral can still have a very strong code of morals. Ethics are different than morals.

For instance, I always saw the Korx like modern international arms dealers - people willing to sell guns to anyone who brought cash to the table, regardless of what they were selling, or the obvious outcomes of that sale.

I think the Korx would have been happy to sell bullets to the SS at the gates of the concentration camps, if the price was good (for the Korx).

Speaking of races I am more so hoping for the custom race section to come back up and running that way we could add back the old civilizations that won't be added in to the official release. But this is Galactic Civilizations so of course there will be custom races. 

I used a Custom race in Gal Civ II. It does kind of suck that a few races have to disappear, but hey, lore is lore. I just hope the Custom Race building is still there and you can go a bit deeper when it comes to customizing it. I always preferred to make my own stories in the Gal Civs universe.

Pretty much this.

They have no ethics code. They will do anything for money - including as the description in GC2 said, sell their own family members off for money.

It's like someone is a psychopath or had antisocial personality disorder, but on a widespread scale.

I just read the databanks ( I know shoot me now )

The surviving Korx are merged into the Krynn and turning it into a crime syndicate from the inside out (rise of the Korx/Krynn Alliance?)

The Torians are being farmed but have the super breeder super ability so can rebuild once freed from Drengin occupation?

The Arceans have survived in small pockets on other worlds (bound to be some on Altaria and Earth?)

Everyone seems to forget the Drath are shapeshifters and probably have members of their race on every inhabital planet and probably have spies/refugees on Drengi and other races planets?

Noone knows where New Iconia is apart from the Terrans and like the Toriens are a aquatic race so they may have taken in other refugee races?

Just some thoughts?

SE3 had the single greatest random event I ever saw in a 4X.  Planets have happiness.  Conquering a planet sinks its happiness to ~30%.  You must laboriously build system-wide joy facilities, set that planet's tax rate low, and garrison it with a surviving damaged troop, to coax its happiness up.

• If planet happiness falls, it riots.  A rioting planet produces 0.
• If a planet is in riot for many turns ... it secedes from your empire and becomes a new AI, which promptly declares war on you .  See Scotland vs. FUK (F = former) later this week

In dozens of SE3 games, I saw this happen only once, ever!!  I spent many games after that trying to recreate it!  AFAIK, SE4 and SE5 eliminated that possibility, which was tragic.

I would pay money for a 4X that allows this to happen!!

• Corollary: The "Rebellion Start" scenario.  There was a sim of 100 AIs against each other.  It was long and bloody.  One AI ruthlessly exploited its conquered colonies, until finally ... a colony rebelled and seceded from all AIs, and became ... You.  On turn 0.  Welcome to the game.  You are surrounded by hostile AIs.  You have just declared war on one of them.  It's coming to take you back.  Fight.

I'd pay money to play that, too.  It's like Robotron dropping into a Mikey level with brains and cruise missiles!
