Just finished playing Modern warfare (2019) Realism difficulty on my PS5. Amazing gameplay and graphics, never had this level of campaign FPS before. This made me hungry for more, I want to understand the lore and story of it all. Where should i start? what games should I buy or what videos should i watch? etc. Im usually the type of person to start/play the very beginning and grasp my own understanding from there. Any tips or recommendations will be appreciated.
