Interesting Discussion! I'm glad I'm not the only one with the "Peacekeeper Plague". I started a number of Dark Avatar games but this is the first one I've really played through. Anyway, in this game, I've gotten the Dread Lords, the unlimited range, the Jagged Knife, the spy's on my planets, the Pirates and the Peacekeepers all in the same game! Both the Pirates and the Peacekeepers really went after my Trade Ships. But fortunately for me, I had built the Galactic Prvateer on one of my planets so it goes after the trade ships after the route is established - but they can't kill them. It does however take FOREVER to process turns in this scenario because the game processes each attempted attack on the trade ships takes 10 seconds each. With a 1/2 dozen or more attempted trade ship attacks per turn, it takes a couple minutes to process a turn just because of that in addition to other events.
I have not tried attacking the Peacekeepers yet - but - I am tempted to try soon just to see how the game reacts. They've attacked everything. Not initially-but over time, they started attacking transports, constructors, etc. if they got too close.

I would be curious to see how frequently all these events happen and if something else might come AFTER the PeaceKeepers that's even worse.

I'm running the 1.6 beta 1 and just had this event happen about a turn or two after I declared war on the Korath. They're destroying EVERYTHING. I can't make a single ship without these guys taking it out. Not a single race is anywhere near the tech level it would take to destroy these things. It's as if the game is just ruined. Any word on what's going on or how to deal with this. It'd be fine if it was on a timer, like they rampage for so long then disappear again.

The worst MEGA event is all planets in a certain area turn to at least 13 base.....I mean come on, I am getting sick of the game I'm currently playing, and more planets, jeez.....this is the worst, I'm on gigantic, and effectively already won this game....AI should just give up....I started pursueing a alliance victory because I'm so far ahead of everyone in terms of everything across the board......have 100 K, an awesome economy, and just owning in terms of tech development.....

Don't get me wrong, I really like Gal CIV 2, but I hate how long its going to take me to finish the game, based on my estimates, it would take me like 2 months at this rate to complete this game. :/

More planets, arggg.......

don't play abundant gigantic maps.....

I had the peacekeepers once. They started to encroach on and destroy ships in my sectors so I dispatched a battleship or two. Once I'd destroyed a couple of their ships they stayed away.

Military production produces ships. So all ships (including freighters and colony ships) will be considered military ships. All starbases are also considered to be military ships. If you have any ships not in your own circle of influence, and that includes planets in other spheres of influence (and also influence starbases), then the ships will be fair game for Peacekeepers. Under these conditions (and it has happened to me - and also with mega event pirates), winning the game requires limping along to a tecnological victory. So, under those conditions, thank your lucky stars (that when you had the chance) you chose to be demonic and squeeze the brain of the galaxy's greatest inventor in your slave think-tank, never letting him rest until he was covered in that special dirt you had him invent, so that when he is used as fertilizer, the plants grow up smart and can continue where he left off...

Seeing as how this event seems to be somewhat broken I usually just reload after it happens.

Sentient species taste better...

I actually did finally have the Peacekeepers event happen in a game a few days ago. I didn't happen to be at war with anyone at the time, and and my influence was stronger than any other empire, so I had no ships or starbases in enemy territory. All other empires had their ships & bases destroyed while I sat back and watched them all get whacked. I avoided being attacked by the Peacekeepers by gradually eating away at enemy planets only within my sphere of influence with both conquest and culture-flipping. Eventually the diplomacy screen poppped up and it was the Peacekeepers...they wanted an alliance with me. So with the help of my supposedly peace-loving buddies, I conquered the rest of the galaxy.

Peacekeepers sounds like they are a fan of an i robot kinda peace

Yea the mega events system does seem to be quite specific in it implementation. Ive only ever had the pirates mega event and the undead one since I have been playing DA. I wouldn't worry about things like these, now that the community has made this an issue its only a matter of time before the Devs do somthing about it, which is amazing as I'm used to playing games like BF2142 were ea's slow and ineffectual support is unbearable.

Just got the game here relatively recently, just finished my third or fourth complete game. I've run into both the pirates and peacekeepers.

Pirates - no biggie was going for influence victory, had plenty of planets, then just switched to tech victory. Nobody could attack me cause nobody could get through the pirates, and there were a LOT of them, and they were tough to boot.

As to the peacekeepers, I expected to be attacked, as they were everywhere, even outside my space. However, they never attacked ANY of my assets - ships, planets, starbases, freighters.....nothing. This was even when I had assets outside my space and NEXT to the peacekeepers. However, they did a heck of a job on many of the evil races in the galaxy. Dren, Yor, etc, etc... I even had the peacekeepers asking me for help later in the game as the Dren had finally gotten back into a position of power and began attacking back in earnest....

Not a clue...

Wow. The Peacekeepers really sound like something big! What happens if the Peacekeepers, Pirates and Dread Lords all appear at once? Do they attack each other and result in a Galactic Clash of the Super-Factions?

Seeing those combined fleet stats, it means that each of their frigates has these stats:

Attack: 3 Missile
Defense: 699 Armor
HP: 231
Range: Infinite
Speed: ???(How fast are they?)

Also, what if they appear when everyone has maxed out propulsion tech and maximized at least one branch of weaponry/defense technology? It'd be awesome to see normal races sending their high-tech dreadnoughts to fight it out against these exo-galactic invaders.

Huge-hulled Capital Ships with maximum miniaturization, Black Hole Eruptors, Aereon Missile Defenses, and HyperWarp 3s, supported by Eyes of the Universe, would easily outclass the Peacekeeper Frigates... except that they would be outnumbered 22 to 5.
Nevertheless, those 3-damage Harpoon missiles would never scratch the Dreadnoughts and the tie rule would cause the overly-defensive Peacekeeper ships to explode.

Seeing as the Peacekeeper ships are robotic, the Yor should love them, and the Dread Lords(who have organic ships) should hate them.

Another thing: An alliance with the Peacekeepers? Is it even possible to ally with races who don't even have a planet and are based outside the galaxy? That way, is it possible to bring up the trade screen with them and try to buy their ships?
