I'm pretty sure that Megacorp adds a few more. Slick Corporation is very excitable.

Also: I'm feeling pretty full of myself, it's just ticked over into the endgame, I've got three 50k fleets and like 80 colonies. In a fit of hubris I decide to open up an L-Gate to see what's inside.

Luckily for me they're friendly, because I go inside and BAM. They have like 5 fleets patrolling that one system that are each stronger than mine. I mentally change up my end-game priorities - Fallen Empires, War in Heaven, THEN the L-Cluster.
