>Is this basically the exact same way people felt when Henry was introduced in fnaf 6?
Pretty much, at least around here. Henry and the books were never as popular as they were elsewhere in the fandom. I can't remember the exact reaction to Pizzeria Simulator (the archives are dead) but I don't think it was like Luke showing up on opening night of Episode 7.
Henry was never a ubiquitous presence like he is in other corners of the fandom. I think the biggest use he's seen is in Springroll's comic.
