Delta Green Players' Struggles

Delta, No Time Travel, Live Broadcast

I want to read a book similar to "Empty the Delta: My Unlimited Withdrawals in the Game". Why is it that Delta is full of time travel stories now? Are there any Delta works that are broadcast live in the main world without time travel, such as knife running, poverty alleviation, and onslaught? As long as it is not time travel, it will work.
