I'd be more inclined to care if it were something with a story that mattered. Yes, that's a tad subjective, but the gameplay of Superhot is its biggest reason to play it. And that's unchanged. Like the creator said, it's a bit of an edgy nonstory about giving your soul away, or something. It was barely there. Star Wars was ALL about its story. The effects from the 70s/80s were a major part of it, that added to the experience and were even historical, for their time. How much do two scenes of making yourself awkwardly point a gun to your head in VR matter to the game in the long run. (and let me point out, in a lot of cases, doing that caused problems for the hand tracking lol)I see this as being akin to George Lucas editing Star Wars, like someone else pointed out. Not just with superhot but just games in general that make changes post launch that you can't revert. Imagine if Nintendo was able to patch out Bowser dropping in to lava in the first Mario Brothers game for the NES because it depicts animal cruelty. It wouldn't make a difference to gameplay but to change a work like that doesn't feel right. Games are creative work and should be preserved in their current state for future generations. This is already the case for films, books, and music so why not games?
And it's quite easy to have the backed-up versions of the game, either via piracy or through recorded footage. This is perhaps the best time to live in for backing up things, as tons of people document every little change made to anything ever online.
That's not to say it isn't silly of them to take it out of the game entirely, but just as Lucas changing the special effects...it's their property to play and mess around with. I think it's a stupid decision either way, but it's even more ridiculous for people to make such drastic comparisons or claim the game is ruined because of this.
