Dont you wanna Play dead rails like the good ol' times, NO?, well too bad

My suggestion is the new "The Good Times" Mode (sorry for any spelling mistakes btw):

This mode contain the old gun system, NO classes and trains, the return of the old selling post, music, and more, also there would only Sterling (no bank), The Castle, Constitution Fort And the Tesla Lab would be the only POI's, and mostly that...
If you win you would get the "Retro" Class, its basicly the None class but you have the classic system (no sprinting, no aiming, and etc)
