I know they did a re-release of the original game pretty recently which supported mouselook for the first time. Pretty cool that they're doing a remake; I hope they have the talent and resources to do it. Making a successful remake (essentially a new game) is quite different from porting older games.
I always meant to play System Shock 2, being a big fan of Looking Glass Studios' first two Thief games. Gotta get on that.
On related news, I found out Nightdive plan on doing a re-release of the PC game PowerSlave with possibly the Saturn version included as well. I've been playing the latter and it's a load of fun; the PC version is supposed to be a completely different game, apparently, using the pseudo-3D Build engine and all the design modifications to fit.
