I've always been fascinated by the idea of a game with two world states existing at once that you can instantly switch between. This concept made for the best parts of both Titanfall 2 and Dishonored 2. The #LordsoftheFallen reboot (yes, reboot not remake) has a living and dead world always existing together and you can change between them and ahhhhhhhh it's so cool! The dead world's aesthetic is just so good!
