Not by a long shot.
I just don't have a lot of free time to spend on it and I am working on some ideas that take a lot of planning.
I'm working on a secondary story that would seem unrelated at first but eventually be revealed as a direct prequel. This will hopefully be done in a comic book style combined with classic doom music and sound effects.
This allows me to come up with alternate explanations for things [like how C24 works] as well as adding a lot of references to the early games.
I intend to skew the story back towards 'invasion from hell' rather than 'science project gone bad'.
