In my limited experience where this has happened they at least gave me a free upgrade to the remastered version, or the deluxe or whatever they decided to name it.A few. Depends on the publisher. Most of the AAA ones pull the originals to upsell you on a "remaster". You can't buy the Steam version of the original Skyrim unless you have the page link itself, for example. They remove them from search results in the Steam app. At least, this was the case a couple of years ago.
