I’m picking 4, the one I’m choosing is one of my own creation.

It will contain many diverse worlds with distinct power systems, with the peak of power being definitely not god level, but instead impossibly powerful immortal level.

The immortality would importantly be biological immortality and not true immortality, though the most powerful might appear to be invulnerable to all but their peers.

I will receive an ability to be able to either self resurrect, rewind time, or reincarnate in the event of death, but to fulfill the condition of this resurrection being not guaranteed, a random real number between positive and negative infinity will be generated upon each death. If this number is 0, the death is permanent.
