Might the lord english situation be a kind of normal event to happen to the game? Because if the trolls got to our universe would humans have gotten to exist and create their own universe, or would it have been more trolls? I guess overall what I mean is; might the big bad messing with other sessions act as a part two to the game, and help propagate genetic diversity in universes? sorry for the wall of text.

Not really, English is a rogue agent separate from the game, and I guess Trolls would’ve played the game again only IF there were no other species, and they conquered everything? The Universe is big, the Planet that spawns the Game could be ANY among the millions and millions of Planets there.
