No, I'm not doing one. After my kill everything / do every quest game, I decided to do the opposite, where I use every possible advantage, skip anything that takes much time and try to stick to the easy and necessary quests. But, I was searching these boards about some other stuff and came across posts about the 5 day game. I couldn't possibly imagine doing that, but my question is: How do you complete the game without the ritual of the void? And I thought you couldn't get that until April after you retrieved Nicolai from a Circus?
I still don't understand how the 1 day travel thing works, but I'll take everybody's word for that.
