Thank you for your reply !
What do you think about : "ALT-F4 : The cosmos has reached its limit with your actions: Initiate a universe reset, including a colossal big bang event, and so forth." instead of nothing ? The idea is similar, but the implications are worse !
I also thought about removing allusions to SCP and replace it by CYCLOP and a random table of anomalies in their vault.
If you mean implying that time is cyclical and everything comes right around back to the exact same point and the exact same sequence of actions, I love the universal and spiritual implications and would love to see it.
I also agree that switching to a dedicated in-doc collection of in-universe objects would be better. The SCP collection is huge, having it be a random one from their archives has a very skewed probability of it not being very good.
