I bought the 2.5 disk version of System Shock 1, and later a CD version in a pack years ago, along with Bioforge, Wing Commander 3.. Pretty good deal for pre Steam days.
Yeah, I'd probably buy it all over again on Steam, if they made it compatible with modern hardware, and maybe added some extras or tweaked the graphics a little.
Privateer, too. They sold it in a sort of "greatest hits" type package, but they did NOTHING to make it compatible with modern tech. And setting up a 95/98 machine for that game is about as easy as going through a step by step boot of DOS, and doing a trial and error disabling to see what works..
