More realism...cool why not ?!
All the points you people have told..are fine ideas, Or platforms for a better JKO.
But we must keep in mind its still a 3D Shooter game.!!
Sure all realism aspects ...would made a game ...more like a simulation... : Imagine this---->
Jedi Knight Outcast...
An 3D Ego Shooter/Adventure/Jedi and Starwars Simulator.
There are a lot of "Setting" which can make a game becomes a expiriance..
But keep the Game in mind.....
