I've been playing a lot of System Shock 2 lately and I got to thinking.
One of the things that lend the "Shock" games a lot of their mood and atmosphere is the numerous amount of audio logs that permeate them. I think it'd be neat if Survivors all started with Universal Recorders to let them make their own audio/text logs. Obviously, the amount of times this would be used would vary from player to player and whether or not people will actually read/listen to them is a coin flip, but I just think it'd be a neat little thing for Survivors to do. Maybe you could tie to the CL and have the CL incentivize the marines to pick up any transcripts/recorders the Survivors have used.
