Is a rebellion still possible?

yup, it's happened to me.  About half of my planets seceded from my civilization.  It may be a mega event...

Hmm. I've heard of a mega event like that (plus the normal Fundamentalists event, which only hits the evil players), but what I'm thinking of is a non-random rebellion based off of low approval, as the descriptions for advanced governments and the manual hint is possible.

The main reason this has come up is that in my current game, the Krynn have the angriest planets I've ever seen in 40-something games. Except where they've built morale structures, every world is at 35% approval, or worse on high-pop planets. Since the Krynn and I are probably headed for war, it would be nice to know if there's any chance of a rebellion coming up and distracting them. (If not, at least Information Warfare should pay off big).

I've seen it happen several times with AI civs, but never my own, in DL.

But the new civ created by the rebellion never seems to do anything at all. I've never even see them build a single ship.

Oh, I hear ya.  No, I've never seen that happen.  But it may be possible.

It is not a Mega Event, since they don't happen in DL.

Qrtxian, it could happen in your game. Don't hold your breath, though. It is a semi-random event.

If you are headed for war your only realistic option is to prepare for it.

I figured out as much in a test I just did: by pushing my tax rate up to 100%, about half my planets did revolt and form a new civilization (which then did nothing). I don't see any way that this could unless you were deliberately trying to achieve it.

What were your settings on DL when you saw it? I haven't ever had a revolution (or more accurately had AIs have one) in many, many games.

The settings shouldn't matter as much as the approval rating.

And besides, I cheat. My people will never revolt.

Besides the random event I've seen it in dark avatar when you try to get more taxes and lower your approval below 50% all the time.

I've had my home planet down to 37% approval without it rebelling. This was with 22% tax rate.

22% tax rate isn't very high; I wonder why your homeworld was so unhappy.

I have a problem, one of the planets sitting in a sector under the influence of one of my allies has rebelled, even though it had 100% approval rating. I think this is a bug.

Also, I've noticed that I can't breake alliance with one of the races (IR), dunno why, but this kind of action is not available in treaties.

Cheers

I'm talking about a rebellion as in a planet or planets breaking away and forming a new civilization. What happened to you was a planet defecting to another existing civilization, which isn't the same thing at all and is based off of influence, not approval. (Although approval does connect somehow, I think).

And now I've seen a rebellion in a real (non-test) game:

It occurred thanks to the galactic disease mega event, which drastically reduced everyone's stats, including morale. This might not be the only rebellion either - the Krynn have yet to research the cure and their morale is at rock-bottom.

I didn't play much longer after it happened, but my notes:

• The rebels don't appear to be building anything on their planets, ships or buildings. I bought two of the Drengin frigates that were ejected after the rebellion and gifted them to the rebels, who are using them - so they're at least smarter then the Vegans et al, which don't make any use of gifted ships.
• The Drengin did nothing about the rebellion. However, they were being beaten to a pulp by the Altarians and surrendered soon afterward, so it's understandable.
• The rebels' race image is a Drengin, but their trade screen is the blue Scottlingas race image.
• They were good-aligned. Possibly rebel civs are always opposite to their parent civs. On the other hand, it could easily be random.
