I have some similar ideas about a story driven time travel game where it's set up so that at one point you face an anonymous enemy, which forces you to trigger certain conditions in the stage and then they escape.

Later in the game you return to this stage at the same point in time, expecting to face that enemy again, but you are this "enemy", and the game nudges you into replicating the exact same sequence of events so that you take the actions which the "enemy" did so your (NPC) past self can replay the exact steps you previously took.

But the game doesn't show this clearly to you the player until you completed the stage - while your character is shown to have noticed something strange, the game doesn't show you the player (or you character's party) that you faced yourself until the end of the stage, using different positions and camera angles to hide it from you and the party. And if you manage to replicate the event chain perfectly, you'll get to see your party members being visibly stunned when you see them realize it was a time loop (your actions in the stage breaks the loop), and hopefully the player can be made to feel like they experienced a time loop, as if they really faced off with themselves twice ("how did the game know I would do it that way?")

In practical terms, Braid is probably closest. You have time rewind mechanics, in some stages it's selective where rewind applies to specific objects AND/OR specific areas (so it's not just try/retry, but actual time manipulation and setup)

Shoutout to Superhot, where time moves when you move (bullettime on steroids)

A Link ~~through time~~ to the past (Zelda), and some more like it.

It's 3D, but there's a Portal 2 mod with time travel

That's just arbitrage

It works until others realize there's an arbitrary opportunity and prices equalize

It's kinda hilarious when the best formula only handles large numbers, not small. You'd think it would be the reverse, but sometimes it just isn't (something about the law of large numbers making it easier to approximate good solution, in many cases)

He's saying the same thing. Because it's not an integer power of 2 you can't have a integer square solution. Thus the densest packing puts some boxes diagonally.

OTOH I only have a PS5 because of Sony's marketing budget, lol (non-slim version included with a Sony phone on contract, so technically also a way for them to clear stock, lmao)

But yeah, I don't know any people with a recent Xbox here in Sweden. In the original Xbox era and the 360 era I think they had a big lead here, but after that I've seen much more Sony represented.

Appears to me meant to handle much larger numbers of users efficiently

Cars use stronger LIDAR lasers than the phones. The bigger range and faster response time requires it.

I've heard stories of clients giving gifts getting pissed when the wrong person claims them, so it's risky for not just legal reasons

The only viable competition to LIDAR is structured light (see Leap Motion, there's equivalent sensors for cars), which uses an IR source with patterned light and multiple high frame rate cameras to calculate depth from the reflections. In theory light field photography with special lenses is possible too, but far more computationally heavy for real-time use IIRC

There's some safety issues with LIDAR at close range (it's a laser! it can damage cameras, etc), which is basically the main reason to not use it. But Tesla are dumb enough to try to replace them with cameras alone, and not even using proper multi-camera techniques to calculate depth
