I have always been a fan of stable time loops so I guess option 2 is the best one for me.

One trope I’d like to see more of is loops which are not stable themselves, but are stable as a group. Eg a 2-loop has loop A in which someone goes back in time and changes history leading to a new timeline loop B. Someone in loop B later goes back in time and changes history in a way that turns the timeline back into loop A.

My headcanon is that your option 3 is basically an n-loop that we only see the first few loops of.

The classic, wrap paper into a large box shape (use a large box as a template if it helps but remove before sealing) then put a small gift inside. Very gently place it where it won’t get smashed, preferably after all the other presents have been placed or way at the back. Someone goes to grab it on Christmas morning and the box collapses under the slightest pressure.

Shadows of Doubt

An alternate universe corpo city filled with generated crimes to solve. You get a case board, scan for fingerprints/footprints, talk to witnesses, look up sales records, check out cctv cameras among loads of other stuff. All of it is happening live in the city - everyone has schedules, an apartment, a workplace, an inventory, an email account, a blood type, a shoe size… - so that murder/kidnapping/robbery literally happened in the game while you were crawling through vents looking for an envelope with sensitive documents that someone asked you to steal. Just yesterday I got to a crime scene super quickly and caught a murderer leaving the scene of the crime with the murder weapon on their person. There are deus ex style body augmentations too.

One of my favourite cases was a woman who got murdered. I had the husband pegged for it but couldn’t pin it on him. His fingerprints were all over the place and he was on the cctv but they lived together so that wasn’t really evidence. The case went cold. A couple of days later the HUSBAND is murdered and I’m stumped. Just go looking for anything related to the guy and hope I stumble across something useful by accident. So eventually I break into the husband’s boss’ apartment and find a bouquet of flowers with a note for the boss from the husband. It turns out the husband is having a secret gay affair with his boss. The boss kills the wife so he can be with the husband. Husband doesn’t want to be with a murderer I guess so the boss kills him too!

It’s occasionally a little buggy still. I was supposed to follow someone, take a photo of a briefcase handoff, follow the recipient and get the briefcase back and have done this type of case before. Yesterday though the handoff never happened and I waited with the original owner for a few in game hours. My guess is the recipient is dead or was someone I knocked out earlier while I was solving another case and I messed up their schedule.
