How often does this happen?

I picked a post apocalyptic empire for the habitability bonus...

I ended up encountering TWO bronze age civilizations in the same system about three jumps from me. Apparently this was the result of a species wide nuclear war over colonization rights in space, leaving both planets in a nuclear winter state (tomb world) and essentially fulfilling the whole "nuke us back into the stone age" sort of cold war cautionary tale. The species on the separate planet diverged into 2 distinct species, with close to the same attributes.

More slaves for me.............. Am I a bad person?

Anyways, after this early gain, I ended up out teching everyone by 2300 (slave labour is wonderous, resettlement is CHEAP) and conquered the L-gate.

How likely is this to happen in a normal playthrough, asking for a friend.

I'd say pretty unlikely, although Post-Apocalyptic is pretty OP at the moment to begin with.

The "twin tomb worlds" thing is relatively common; I see it in most games.
On the other hand, having them close enough to your starting point to be a significant boost requires some good luck.
Post-Apocalyptic is wonderful. I especially like it as Fanatic Purifiers, since they can turn any world into a Tomb.

the two tomb world pre-ftl civs are distant stars content and I think they are guaranteed to spawn when distant stars is activated

Oh the hazards of surviving nuclear fallout.. you will adapt to enslave all other aliens
