I haven't played in a long time but I remember buying a GeForce4 Ti 4800 to play 1942 and wanting to upgrade to a 8800GT to play Battlefield 2 and have fond memories of spending potentially thousands of hours of my teenage years both at home and at internet cafe's enjoying these games and their expansions or other sequels.
Battlefield offered huge, climactic battles that at the time was unheard of, revolutionary and even today non-Battlefield titles try and sometimes do recreate.
These maps feel claustrophobic and these mechanics like hitmarkers and lean-peeking around doors is just so cheap compared to other games.
Some things can be fine tuned like the AA vs Air or Medic guns underperforming, perhaps even the animation deaths cleaned up but more than half of the maps are so packed in that everything takes place within a city block of each other.
I own RS6:S and Blackops 4 and can really excel in both of them, but when I feel like I want to excel in Battlefield I need to opt in to Assault and just play CoD at the objectives.
