The first time NJTS was delayed, I decided to make a game called "Nik Jam the SAGE" that was short and simple, and call the one I'm working on Nik Jam the SAGE 2. Later on I didn't like the idea, since Rescue Mission was the one that I started first. So this was renamed to Nik Jam the SAGE 0, and Nik Jam the SAGE/Nik Jam the SAGE 2 was renamed Rescue Mission. But the game still refers to Nik Jam the SAGE. I was going to throw this away to oblivion, but it has some nice stuff. A Re-released version with gameplay and cutscene changes was released at SAGE 9. A second re-release was made in 2007, which added a sheild feature and updated the graphics.
Nik Jam the SAGE: Rescue Mission SE 2007
As a SAGE project, I wanted to make something SAGE related for Nik Jam, there was a character called Nik Jam the SAGE that was used in every SAGE since SAGE 2. So I decided to make a game out of him. It's called Nik Jam the SAGE - Rescue Mission, delayed twice, it's finally released in it's entirety, but with a heavy price. It's very glitchy, but uses INIs to save your game just in case the game crashes. A special version was released in 2007.
