CD-ROM VersionThe DOS CD-ROM version boasts an enhanced soundtrack, but otherwise appears to be identical with the floppy version.
Copy ProtectionThe requirements sticker for Future Wars: Adventures in Time also mentions "Color Monitor Required". This has nothing to do with the game, but is rather a requirement of the copy-protection, which refers the player to a color-coded picture on the back of the manual and asks them which color it is. This was an effective way of foiling pirates who photocopied the manual, as photocopies don't contain color.
EGA GraphicsIn the DOS version of the game, when choosing EGA graphics, Lo' Ann's hair color will be black instead of brown as it is in VGA or the Amiga version.
MusicThe PC speaker soundtrack programming utilized the technique of interleaving notes from more than one musical part. This ultra-fast switching of notes gives the impression of polyphony even though it was strictly monophonic. While many games did this, Future Wars: Adventures in Time was one of the most outrageous. Up to 4 separate musical parts can be heard simultaneously in the introductory track through the PC speaker.
Operate CommandThe game introduced the command "Operate" for interaction with objects of all kinds. It is basically a substitute for the common "Use" command. "Use" is in the verb menu nevertheless, but it's for applying items only. Although "Operate" was used only twice, in Future Wars: Adventures in Time and the subsequent James Bond: The Stealth Affair, it has become a trademark of the early Delphine adventures.
ReferencesThe magnetic card found in the monastery has the words "Bio Challenge" written on it. Bio Challenge is the name of an earlier Delphine game.
