[MW2] CoD campaign idea: Realism mode should let you build your own loadout before each mission.
In every CoD campaign realism mode just removes the HUD. That's it. My idea for future Modern Warfare titles — realism mode unlocks a pre-mission loadout screen. You read the mission brief, assess the environment and objectives, then build your kit accordingly. Wrong loadout for the mission? That's on you. Brought a sniper to a CQB mission or an SMG to an open area op? You deal with the consequences. It would make every replay meaningful and add a real decision making layer that no CoD campaign has ever had. Basically what Wildlands does but inside a linear cinematic campaign.
