That said, the KS campaign has been pretty clear that the remake will involve "improvements, overhauls, and changes":
A modern take on System Shock, a faithful reboot; it’s not Citadel Station as it was, but as you remember it. Many improvements, overhauls and changes are being implemented to capture the spirit of what the original game was trying to convey, and bring it to contemporary gamers.
Though I vehemently disagree with bringing Chris Avellone into the project -- increasingly it feels like he's the only legitimate writer in business -- I'm okay with the general impulse of refining the original experience. The project doesn't (at least explicitly) aim to make "today's gamers understand why the original game was so influential", it's more like massive fan service a la the original big-time gaming KS wave of 2012-2013.
And why be concerned about the slight modifications to gameplay when the completely overhauled visuals themselves present the largest obstacle to appreciate System Shock for what it was? They won't be playing that game, yes. But they never were going to be. Let's not mistake the past for mere nostalgia. If Night Dive does a good job with this remake, a group of contemporary gamers will appreciate the System Shock name, and hopefully they won't be consigned to conventions of 1994 in the process.
