System Shock. And Dungeon Keeper.

S
Well, you shall be heard:
systemshock.com
There's even a very early playable demo:
A first-person fight to the death in the depths of space!

As for "System Shock 3", which i also have seen mentioned in this thread, be very very careful about that one.
Yes, it will be made by OtherSide Entertainment, who're basically a reboot of (dare i say legendary) Looking Glass Studios, including Warren Spector and Paul Neurath,
Creators of the original "System Shock", "Thief" and "Ultima Underworld".
However, their spiritual successor to "Ultima Underworld", a game called "Underworld Ascendant", turned out to be an abysmal mess which has been all but abandoned.
It pains me to say this, but i hold no hope for SS3 whatsoever.
