A series of one shots or minicampaigns for 2400 where we play all the different 2400 games but sometimes reuse characters or reference events to inspire new characters or use former NPCs as PCs etc etc etc. Just an early brainstorm because I like all these.

Yes please!

So far I’m trying to make them plausible to exist in the same universe, but separated enough by space (or time?) that they could potentially have wildly different levels of technology. 

You've gotten me thinking about how I might do this soon. I'm considering starting with a Cosmic Highway crew on a job that takes them to Prospero's Dream from A Pound of Flesh, which introduces cybernetics from Inner System Blues and illegal resleeving, with a tip that they can get resleeved legally in Alpha Centauri via CTRL. And somewhere along the way, I want an excuse to run them through Dead Planet and Gradient Descent. (I love Mothership modules.)

Great idea.

Now throw in the 24XX games from the Jam!

Of course, that's what Tempus Diducit is for!
