My ideas:
JJ1 Technoir (just because)
Airbase (I'm thinking of making one especially for PIPE PROJECT)
Laboratory (Labrat barely looks like a lab for me)

Internet would be cool. Using e-mails as warps, graying and ungraying stuff by triggers, hacking restricted websites, fighting viruses... whee! ^_^

What I'd like to see too are JJ2 tilesets redrawn in JJ1 style. I like JJ1's style.
