With the Guest's addition in the Halloween Patch, it kinda feels like we're missing out on some potential to spice up the Act 1 gameplay. If I recall right, in the intro Quentin hears the Guest after waking up in the banner for the first time but he never appears again until when/if the player enters the forest.
So, I thought of a way to solve this: Change the night time sequences to have The Guest as a antagonist. It also would make things better than just Quentin constantly passing out.
The general idea is that on each night, Quentin retrieves the items that he normally goes for, like the Shovel, the photo, and the Camera. However the difference is that instead of randomly passing out, Quentin would stay awake and have to get back to the banner. This is where the new gameplay comes in.
When Quentin tries to go back to his Banner, The Guest would be stalking him and trying to prevent him from getting inside. Perhaps there would be ways to keep him at bay, like using lights or hiding in trash bins to wait for him to leave. Going inside of residences would mark you as safe, but if you taunt him by constantly leaving and going back in then Guest will lunge for you.
In free roam, the Guest is still a threat. Showing up when time transitions to Night and disappearing when the sun starts to rise. Maybe the ability to sleep again would return from the Beta as a way to combat this as well.
