The Stanley Parable: Ultra Deluxe is now "content complete" and will launch in early 2022. This news comes by way of developers Crows Crows Crows and a new trailer that pokes fun at themselves for the development delays thus far.
Ultra Deluxe is an "expanded re-imagining" of the original game from 2013, in which you played as Stanley, an office worker whose actions garner responses from a glib narrator. You can do as the narrator says, or rebel against his comments, and the narrative spins out in funny and surprising ways I won't spoil.
This is that but again and more, I guess, and possibly different. Ultra Deluxe is being made by Crows Crows Crows, the team founded by one-half of the original Stanley Parable development team, William Pugh. Crows³ have also made games like Accounting+ and the free (and excellent) Dr. Langeskov, The Tiger, and the Terribly Cursed Emerald: A Whirlwind Heist.
The remake was originally announced back in 2018 with a 2019 release date, so it has had a few delays since. That it's now apparently so nearly done means it has a new Steam page on which you can wishlist it.
