This Star Trek card game. It’s called Fleet And Federation and imagines what would happen if a setting like the original series was a well-edited reality show (which allowed me to mix in navy events and Hollywood development events into the mix). It’s a co-op game that tries to operate as a fast(er) action TTRPG, the end result of occasionally getting face time with my old gaming crew but not having time enough with them for a proper TTRPG campaign (or even a run)
I worked on it a long while before giving up for lack of local playtesters and venues. In retrospect (having since learned more design theory online), F&F would suffer a bit from quarterbacking, but otherwise was fairly viable a working game.
That said, I was quite proud of countless diegetic elements of the game and would sometime have to explain it to someone, but first explain what the hell F&F was so that they’d know what I was talking about, and by then their eyes were thoroughly glazed over.
