I am actually currently idea working out something kind of up my alley as it were:

What if there was a game that allowed for not only generally realistic military style combat... but also enabled highly skilled players, or players who practice a good deal, to be able to pull off some John Wick style bullshit thats always been impossible to do well in a multiplayer game?

My current concept is that through taking advantage of the Steam Deck's unique control scheme, I can essentially more realistically convey both the pros and cons of gunplay and essentially bits of MMA/CQC style stuff from action movies or like MGS cutscenes.

Its likely going to take me a long time to fully attempt a demo of this, and it may not work at all.

But, im currently unemployed, living off of disability, quite fine without much in person social contact and i actually have a lot of experience writing code of all kinds after a decade in the tech industry.

It could absolutely all fail, but even then, I'd just have fun in the attempt.
