To make a good video game, certain laws of physics can be ignored. For example, if I am floating through space killing ice aliens, I REALLY want to be able to use my flamethrower. (I’m not sure if that game exists yet, but if it doesn’t… free idea.) Unfortunately, boring old reality dictates that in order to burn, fire needs oxygen, of which outer space is lacking. Ignoring this truth leads to a much more enjoyable rampage, and in the meantime I could still accidentally learn a thing or two about the laws of universal gravitation. One actual video game series that runs with this concept of adapting physics is Portal. In Portal, you control a human test subject that obeys all the conventional laws of physics. However, your character has a gun that can create a wormhole between any two surfaces you shoot. Jump in one portal and you emerge from the other. Put one on the floor and the other on the ceiling above, and you can fall through an infinite loop.
