The "Duke Nukem Forever" of a certain game genre or category...

[Segataritensoftii]

Out of all the games in a certain Genre or category of game, which one would you consider the "Duke Nukem Forever" of that particular one? I use "Duke Nukem Forever" to describe a particular game that spent or is spending a really long time in development and was either canceled, is barely alive and nobody's doing anything with it, or IS being actively developed, but just taking a really long time to release a new binary (3+ years). Examples of what I would consider the DNF of something are Sonic Robo Blast 2, mentioned in an earlier topic (been in active development for almost nine years and still hasn't gotten beyond Sunflower Hill and Techno Hill zone), and Man Goes Down on the Atari 2600 (Cover art and manual were made and game was almost ready to ship, but maker got sick and the game has been on hold for nearly 2 years.). I even have a few fangames that I planned that I would consider DNFs, such as Sonic Tempo (me and my brother were planing it for years, but never got past the title screen development wise), a version of The Incredible Machine with parts and environments based on popular video games (had a lot planned, but never got around to making ANY of it) and, to a lesser extent, my latest project, Jumping Flash 4: The Rageful Revenge of Baron Aloha. This project has spent a year in planning now. I'm currently saving up for a Macbook so I can have a computer powerful enough to fulfill my ambitious resurrection of the heroic robotic lagimorph. I actually thought out the gameplay aspects, all the extras that were to go in it, finalized a soundtrack, sketched out lots of concept art, and actually did a lot of the in game voices on my trusty Macintosh LC. Now the only thing standing between me and actually making the game is $1099 for a shiny new Macbook. *sighs longingly*
