Alcoholism and drug abuse during work hours

or

Cultural genocide against indigenous people

Adopting wild dinosaurs/Animal hoarding... Paleo Pines. It's like the rated G version of ARK. I've got 45 super cute dinosaurs, but because this is a game, I'm rich enough to be able to give them wonderful lives!

Uh let's see, destroying infrastructure with armoured vehicles, being involved in and actively promoting a multi generational world war, genocide, arms dealing, piracy, war crimes.

breaking the sound barrier inside of a mountain

Trying to escape Hell.

As for the actual last game I played, terrorism maybe?

Destroying a coal mine with magic

Driving around on a bike that would get ticketed for too low speed and killing everything and everyone that I come across (Days gone).

Piracy lol (Sea of Thieves)

Broke into some noble’s house to investigate a murder and stole a bunch of stuff while I was at it, ironically yet stealthily stabbing a guard in the neck with a dagger so I wouldn’t get caught while discovering a secret chamber in the basement that led to ancient catacombs beneath the town, which ultimately led to ancient and mummified remains alongside golden chalices and crosses I absolutely pillaged and fully intend to sell for ducats, the significance of which I’m still unsure of.

Pickpocketing the same person 100,000 times.

Illegal establishment of colonies
