A recent Freakonomics podcast said "... people fall prey to what economists call sunk costs, once you've invested a lot in something you hang on to it even though it's not worth anything". With one arena left to design, we decided to make a zombie graveyard. We bought the assets and spent time designing the arena, modifying textures to match our style, adding features like bioluminescent trees and grass, ensuring the gravestones glowed, etc The Freakonomics podcast summed it up perfectly "... it would have been so easy to say, okay, it's not exactly perfect, let's just keep going". We found ourselves with a choice to make; do we stick with an okay arena that we've already invested time and money into and try to make it work, or do we scrap it all and start from scratch. We chose to create a brand new, clean and simple arena, that we are excited about. It's extremely difficult to walk away from something that you've invested time, money and heart into, but in our opinion, this is a skill that is required in order to be successful.
