The Enhanced Edition is a significant improvement that I'd say is well worth the $10 asking price. It's undoubtedly the best way to experience a game that had been unjustly forgotten, a game that was in it's heyday both wildly innovative and painfully backwards. That 'backwards-ness' is substantially improved here, resulting in an experience that is quirky but not uncomfortable, though it does have a learning curve... it took me an hour or so to get adjusted. Patience is required. The music is great, the gameplay is immersive, and the antagonist is deservedly iconic. It's not flawless, but I highly recommend it. Additional thoughts: The only weakness I found in the story came with its ending -- the build up is excellent, but once the finale is reached the game concludes almost immediately. It doesn't give enough time to take in everything and feel satisfied. But, I suppose the journey is more important than the destination. Some have described System Shock as a sort of Metroidvania, and I'm inclined to agree. Citadel Station consists of 9 decks (levels) connected by elevators. Aside from collecting keycards and solving circuitry puzzles, you'll need to find character upgrades in the form of environmental equipment to progress, and this sometimes involves back-tracking to previous decks. System Shock wasn't designed with mouse-look in mind at all, so interactions handle somewhat like a Point&Click Adventure game; inventory management is handled in the bottom half of your HUD, not in a separate/pop-up menu (and the game doesn't pause while you're sorting through your gear). For example, rather than reloading being bound to a hotkey, you reload by clicking an icon in the lower HUD -- you must move your cursor off of your target and down into your HUD to reload. Overall, System Shock supports more methodical, slower-paced fighting that is the complete antithesis to DOOM.
