Better play it today, because after 2028, you're never getting the achievement.
Unless steam updates their font dependencies somewhere in the upcoming 16 years, of course?
On the other side this post reminded me that is has been several years since I last played it, so I will check if I am eligible for the achievement.
I continuously spent over 25 years of my life not playing the Stanley Parable. If I have to twist the Narrator's arm to force him to realize it, so be it.
