They brought the impact on themselves by having the remaster be a rebuild of the crappy mobile port. One of the most well known games ever and they treated it like trash.
>... this isn't strictly true that it has no impact on Rockstar at all.
You're right, but you're right because you're arguing against a statement/point I never made. :)
There's "next to no loss" (I did choose my words carefully...) because people will continue to buy the remastered versions for the consoles they were released for. The only segment of people Rockstar may or may not lose out to are the people who are going to go to the effort to port this to an old, defunct console (one that Rockstar doesn't even see profitability in, since they don't have a version for it), but even then this project requires a legally purchased copy of the game in order to get started.
So now we're into a fun legal/moral area of, "I've purchased this game legally, and I've purchased this console legally, and now I would like to use both together".
