For people that own BOTH Prey 2006 on Steam + Prey 2017 on Steam -
be careful.Giant Bomb on Quick Look at 12:56 mention you CANNOT have Steam-versions of both installed at once (at least on the same drive) -
https://youtu.be/lY4ZHKrAqlc?t=776Prey 2017 uses SAME Steam-folder directory as Prey 2006. WTH?
Also been talked about on NeoGAF -

If you have Prey 2006 from retail on disc (i.e. the Non-Steam version) - you could install Prey Classic wherever you want (probably don't want to name the folder Prey, just to stay safe); patch it up to 1.4 (DRM-check removal patch - you can get that from 3D Realms' Web Site); and just run that version of the game.
You can always add that as Non-Steam game, to do screenshots + all of that stuff. Tested it, works fine.
Also, Prey 2006 retail-disc keys can be activated on Steam. Check the back of your Prey 2006 manual for the key + register that onto Steam.
Also - yeah, you might to download Prey 2006 Steam-version and back it up elsewhere before you mess around with it - since it's only around 1.7 GB or so. Probably easier to back that up than whatever size say Prey 2017 is.
Plus, Prey 2006 is no longer getting updates anyways - and that likely won't change. We already known Prey 2017 will be getting updates, at least to fix up FoV issues.
Since Prey 2006 Steam-version's EXE is protected w/ Steam-DRM, that version doesn't work without Steam. So, if you have both Retail + Steam-versions - you could do this:
1. You might want to back-up the old Steam-version Prey.exe somewhere, for back-up purposes.
2. Copy the DRM-FREE version of Prey.EXE into the Steam-version's folder.
3. Re-name Steam-version of Prey 2006's actual game folder (i.e. rename it to Prey 2006, Prey Classic, or whatever - i.e. rename it to anything but Prey, since Prey 2017 wants that directory)
4. Add your Prey 2006's own Prey.exe as Non-Steam game.
Tested it; works fine.
Also, PROFILE Folder/Saved-game folders for Prey 2006 + 2017 are different - so, at least those two have different directories for Profiles.
Prey 2006 profiles goes in My Documents\My Games\PREY
Prey 2017 profiles looks like it goes in My Documents\My Games\Arkane Studios\Prey, according to
PC Gaming Wiki for Prey 2017.
I don't have Prey 2017 yet - but I guess you could always puts Steam-versions of Prey 2006 + 2017 on maybe different hard-drives?
Not sure if Prey 2017 would overwrite Prey 2006, if they are installed on separate drives.
