You can create something not possible in real life, that's why there are pirouettes and signs.*Gets more popcorn and cider*
This is getting interesting... I always thought that one big + in games and fiction was, that you can do things that aren't possible (or practical) in real life. Oh boy, I was so wrong... CDPR should make Sims next!
But you can create the impossible only within the extablished rules of that fantasy world.
