C.I.T.Y. 2000 Paris (non-existent sequel of PC adventure game; 1990s)
Excerpt from the back cover of C.I.T.Y. 2000, mentioning a sequel.
Status: Lost/Cancelled
C.I.T.Y. 2000, also known as City in Trouble Year 2000 is a point and click adventure game with puzzles, developed by Rollogame Ltd. and released in 1993 by Aditus, Inc. You play as Jon Daring, an American secret agent on a mission to stop the evil drug lord S. Rooter from taking control over London. The game uses a classic inventory system and live-action cutscenes.
C.I.T.Y. 2000 itself is not very rare by definition, since few copies can be bought on eBay and Amazon; the game also has been ripped and its digital copy is circulating online. However, the sequel made the next year, entitled C.I.T.Y. 2000 Paris (or City in Trouble Year 2000: Paris) never made its way to the Internet: there are no copies available on any abandonware site, nor on trading or selling websites. There are currently no website clearly documenting this sequel either; in fact, the only proof of existence of C.I.T.Y. 2000 Paris is the back of the C.I.T.Y. 2000 box mentioning the lost/cancelled sequel and the CD-ROMS in Print catalog published by Gale Group: the 1996 to 2003 issues all indicate that Aditus published this game in March 1994 - with Jon Daring as main character again. Another notable thing is that according to the Gale Group catalog, the game was/would have been entirely FMV (Full Motion Video) as in a Night trap style interactive movie game. At least that is what it's apparently trying to say.
Very little can be found about the two companies: Rollogame has been involved in the making of at least 3 games (C.I.T.Y. 2000 for PC, Castelian for NES and Dream TV for SNES) and Aditus was a Montreal-based publisher. The sequel to an obscure game can sometimes be even more mystifying - in C.I.T.Y. 2000 Paris' case, the efforts of several collectors haven't reached any fruition yet.
Due to it's obscurity it wasn't likely ever actually released. And if it did, then it's "release" would have had to been very limited. But the question is how far along it ever got into development. Whether it was finished or not, or even ever made we still have yet to find out. But unless the game ever sees the light of day we may never know.
