SS1's final cyberspace maze is one of the few decent ones - while the underlying cyberspace mechanics are undeniably quite poor, the layout is at least more interesting to explore than the usual, with some loops and optional areas. Arguably the best cyberspace mazes on offer can be found in the
System Shock: Rewired fan mission, as they're focused more on exploration and flying challenges (lots of mines to avoid in tight corridors) than the godawful combat.
In my opinion, SS2's cyberspace nostalgiagrab sequence is the only bad content in the entire game. I will gladly defend the Rickenbacker and the Body of the Many because I think they're genuinely great levels that put your skills and resources to the test, but SS1's Bridge level easily beats SS2's "Where Am I?". There's just nothing there in the latter -- seeing Medical again with flattened textures and lighting isn't cool, the enemies and floating hurt blocks are boring, and there's barely any actual level design to speak of. Given more time, they could have had a mind-bending sequence filled with combat, security systems, traps, and platforming sections, possibly mashing up redone bits and pieces of Citadel station floating in vectorized cyberspace as you complete some final objective to unlock SHODAN's hidden lair. The issue of the Many being dead presents a challenge for enemy variety, though perhaps some enemy models could have been retextured and repurposed as mutant creations from SHODAN's memory -- I certainly wouldn't have bat an eye if the overall encounter design were good, as the game has all but narratively jumped the shark by that point anyway.
Both SHODAN bossfights are pretty bad, though SS2's at least has a few solutions for different playstyles and requires more from the player than just battling your camera controls to mash RMB on a blue cone sprite with zero hit feedback (did I mention cyberspace combat is terrible?) until the game rather arbitrarily decides it's over.
The shitflinging contests about which System Shock is a perfect masterpiece and which one is overhyped garbage liked only by [insert generational pejorative]s who just don't
get it, man are pretty idiotic. Granted, I'm happy to join in and dunk on SS1's braindead combat AI, poorly fleshed out mechanics, unbalanced resource economy and so on, but it's only because I prefer SS2 by a decent margin and many of the people in this thread are applying one critical lens to the game they love (which emphasizes the warm fuzzies it gave them) and a different critical lens to the other (which emphasizes the COLD HARD FACTS about its shortcomings). Guess what, both games were highly complex, hugely innovative, and also fairly flawed. The first game isn't trying to be as much of a survival horror FPS/RPG, and the second game isn't trying to be as much of a dungeon crawling Metroidvaniawhatchamacallit. Which game you prefer will depend on how much you value each type of experience and what you expect about its execution, and some less tangible stuff like atmosphere (as well as complaints about SS1's interface, I suppose, but quit being a baby and just go play the SSEE source port
without hotkeys). I love both games, but SS2 is second only to Deus Ex as my favorite game.
You may now resume your tirades about boomers/zoomers who have the wrong opinions about two games that are four times as old as there are years between them -- it is certainly revealing of how little the medium has advanced in the meantime.
