I recently played “Dying Light the Beast”. The game is well made but all the zombies are only a few types and look the same. I would like to ask if it is possible to change the engine itself so that the computer can make random combinations of different options to create the zombies. Then the variety will be even greater. The same applies to the vegetation that surrounds the abandoned buildings or the rust on the cars as well as the damage on those that are not moving. If the computer randomly combines different possible options then the games based on this engine will look much more realistic!
