Yeahp, I have to agree with you on numerous things.... the campaign was a little thin, too thin actually but it had a good story line! Very good actually.
As for the multiplayer aspect it was wild as hell! It's a shame the servers died out ey... I've got like 1.5k hours in multiplay with BF4 🤣🤌
And for the games after 4... well they never really cut it for me either... although I heard Battlefield 2042 is pretty great? I have never tried before though!
But replaying the campaign again now after 10 years! Feels amazing!!
