I just finished System Shock 2.
It's an amazing game! I really thought that it might suffer from having a great start but little substance during the ending levels but I was VERY wrong. Shodan has to be one of the best characters I have seen in a video game yet. If you have not read the following article than please read it.
I was worried that I wouldn't be able to run this game on my newer computer but a bunch of patches, fixes and some manual typing to get my video card to work with the game later I was running it.
What can I say, it's ten years old and it's still GREAT. I can fully see myself replaying this game again in the winter playing as a Psi-class character.
