Well, lets see if any of these suggestions find a home.

Emergence: I was thinking a cyberpunk game ala Shadowrun would be fun, but I have issues with Shadowrun (it's ridiculous crash mechanics for example). With that in mind, I found Emergence by chance and I absolutely love everything about it. I would be open to keeping the original setting or going with the real world with magic (similar to Shadowrun), depending on the GM's wishes.

Code 2050: D&D. And Cyberpunk. Not sure if I need to say much more. Hoping someone else has the current playtest packet and is willing to run it, but I also am kind of understanding that it might not be too well known.

Ops and Tactics: A little known gem of crunchy but sensible modern tabletop rules that is completely free. I'd be happy to play in something as "common" as a modern police procedural style game, all the way to a post modern cyberpunk setting, to something in between with magic (like Bright, I know the movie isn't great but the setting and lore are awesome). The rules are versatile enough, but it's really up to whoever wants to run it. (I will note that it is D20 inspired, but not a D20 system)

Hopefully there's someone interested in making one of these happen!
