One of the many things that intrigued me about the Gameoverse is its interesting yet cruel worldbuilding.
The idea of your heroism that leads you to save the day and beat the villain being the thing that dooms your world is terrifying. What's worse is that you cannot tell the hero about that as it breaks the rules and the only time the hero will know that is if it's too late and their world is about to be destroyed.
I sort of understand Warrick's motivation even his methods are extreme; I too wouldn't like to live in the world like that and I would do anything to change it.
How many heroes besides Kit have been severely traumatized that their heroism have killed off their loved ones and the world? How many have been ridden with survival's guilt, PTSD, or madness because of that? I wouldn't be surprised if one of the many video game heroes have gone full villain so they wouldn't destroy another world. If heroism destroys worlds, then villainy will save it.
Besides that, I would love to see other video games worlds of different genres, such as open world, cozy games, HORROR, and many more. I would kill to see a world like Stanley Parable or any mascot horror game.
I already can see people drawing existing video game characters as residents in the Gameoverse. Lots of crossover potential.
