Jones in the Fast Lane
Trivia
Development
This game was developed externally, and shopped around a few publishers before Sierra picked it up. At that time, all the game mechanics were there, but the presentation was all very "comicy", and there was no music or sound at all. Sierra added the whole yuppie look and feel, and this game was one of the first to include digitized actors and superior Roland Sound (which was ported to the CD version).
Title
Jones in the Fast Lane was originally titled Keeping up with Jones for the obvious reference to the phrase "keeping up with the Joneses", which refers to the desire to have at least as much wealth and success as your neighbours/peers (which is exactly what the game is about). The details are unclear, but someone somewhere owned a trademark on the phrase, so Sierra changed it.
Different DOS versions
At least three different versions of the game for DOS are known to exist: Floppy with VGA graphics, floppy with EGA / Tandy graphics and CD-ROM with VGA graphics and Audio CD.
