I tried out this crisis starting from the beginning. I have to say while the idea is neat, it's execution was a little underwhelming compared to vanilla crisis. I'll cover some of my notes here.

You have to use either black holes or neutron stars to build the required structures. They only cause more anomaly investigations to come up. And chew up whatever you build them around.

The technology you get is limited to 2 beam weapons, powerful jump drive, a good shield tech, and a starbase temporal field. Now these are very good, but i would have liked to see some more tech based around time manipulation. Things like buildings that accelerate resource production.

You also get the ability to run an espionage that deletes an enemy from the game by erasing the civilization from time. However, you get this along with the jump drive at the end of the crisis chain. This also automatically starts the end game situation The End of Time. This wins the game and there's not really anything involved in it accept to turtle up and wait for the timer. I would have like to see some more involvement there.

Tldr: while I love the idea, I think it could still use some work to bring it up to the same level as the other crisis
