That's what quick and dirty re-releases are there for. People see 'new' re released titles with in a few extras, updates and DLC and bam they can charge full price for them. Iirc from sales figures of recent cross platform titles people generally move quickly onto new consoles when they release (granted if they are in stock and readily available). Sony and Nintendo or whoever does the remasters/remakes put little effort and get money back. Have to consider as well that retail games generally lose value (outside of Nintendo ones) due to a various reasons like retailers stock space, shelf life etc.
Going into console history.. if we go back in time, PS was very BC-centric until the PS3 which broke PS2 emulation outside of the first models, same with PS4 and they realized they could make more money from reselling legacy games on newer platforms. Either way I don't see companies backing this approach. Xbox has massive backing from MS and huge resources and want to complete as much as they can so they can say stuff like this. They can bleed some money to gain marketshare while others don't have that luxury of supporting and patching old games to work on their new machines.
I've read that people spend an extortionate amount on ships and stuff. Nine years later and still in alpha stages and no actual release schedule or time frame for completion. It just screams vaporware to me. I mean yeah you would have thought a reasonable person or backer would have caught on by now xP I guess if backers are having fun with the builds though tbh its looking like the 'game' they bought is never going to be finished.
