Many people own and played the original, myself included. When the remaster was announced, I looked at it, and it looked like exactly the same game to me. I didn’t see a reason to purchase the game again.
It completely passed me by. This is literally the first I’m hearing of it
I believe I only saw the game being “announced” because I follow a currator on steam that highlights games being de-listed soon. And at some point, i got notified about Braid being delisted soon, because of the remaster.
There was also a fairly high introductory discount for people who owned the original on steam, and it dropped to a 75% discount only a month after release.
