I have 100 and 144. I do tend to like 100 better, but it’s not something I lock myself into. Depends on my budget, free space, gumption, and the model itself.
As far as moving with gunpla, no, but I have moved with minis from Warhammer and such and have had no issues as long as I used good carrying cases. Maybe try some rubbermaid containers and pluck foam?
Yeah I want to see how this plays out. I imagine they focus more on the psychological horror aspect of “be afraid of the dark” and maybe have MC talking about the weird fish he’s been catching to another character. Then have a reveal of one at some point to scare the pants off the viewer?
