No resleeving would also kill fork swarms and restore the continuity of existence that makes actual risks meaningful. Being limited to a single body also actually allows all the identities as straight/gay/trans/attack helicopter to mean something.
It also creates something that can function as a game economy of sorts for the players despite the post-scarcity economy in that a body can only support so many mods at one time.
It’d definitely slide the game back towards a more comprehensible setting; though at that point one would have reason to ask whether retaining the game’s engine is even worth it or if switching to a stronger system wouldn’t be better.
An excellent point, since so much of the game 'engine' is bound up in the 'sleeving' system.
I don't object to medicine that is close to miraculous -- like, being able to reconstruct neural pathways, and short of being outright incinerated you can probably be revived. Think how Arthur C. Clarke revived Frank Poole in his novel 3001. But existence should mean more than being rebooted from a backup.
Here's my thumbnail thought on revising things in the setting.
Earth is still screwed. However, nobody knows how many survivors there actually are versus how many got off planet. As various sapients were evacuated, the TITANs seemed to become distracted, apparently 'forgetting' what they were doing. Hence how some many living people escaped.
Many refugees are still stored in cryostasis systems, slumbering, because there's simply no place to -put- them and they will have to be retrained and educated on the realities of post-Earth existence.
The Lunar-Lagrange Council and the Planetary Consortium still exist. 'Rusters' are human stock with biogenic modifications that allow them to survive the Martian surface. These traits breed true, much to the PC's irritation (because it's getting harder and harder to sell Martian mods).
The Jovian Republic isn't full on Luddite, but it's notoriously insular and VERY backwards when it comes to computers and mesh technology. Few Jovians have mesh implants (whereas most people in Sol space have them) and use terminals and pads instead. However, this also makes Jovian systems almost ridiculously hard for computer hacks and viruses to penetrate. AIs are also very banned; think Dune/40k Imperium of Man levels of 'no AIs'.
Firewall is a distributed defense system, run by the Prometheans; these are TITAN-level AIs who avoided going down the TITAN route and opted to protect humanity. They RARELY interact with PCs; if a Promethean has to talk to the party things are VERY serious. Because the Prometheans have their digital fingers in a lot of places, they are able to tweak and influence things to 'smooth the road' to an extent for the party.
Uplifts are still out there, but are confined to pigs, dogs, cats, octopi, dolphins/porpoises, and primates. No whales (seriously, wtf), no elephants. AGIs exist but only on hardware that won't allow them to expand into full on TITANhood.
