I hadn’t thought about it, but citizen sleeper and road 96 actually do have quite a bit in common. However, they are very different tonally and in the moment to moment gameplay. I haven’t finished road 96 yet but while I agree that citizen sleeper is a better game, they are also both enjoyable for different reasons
The need for decentralised identities stems from the same problem you are describing in your second paragraph. A decentralised identity would imply that your content will also stay if the instance goes down. I don’t really know however if there is a feasible way to implement this. An easier solution to me seems to be to enable account backups that can be used to recreate your account on a different instance.
