Its always about the people.
Having fun with some friends is hard to beat with BF.
Me and a buddy in BC2 was basically killing the other team and winning matches as the rest just stood in a spot and shot back and forth.
Buddy didn't know you could press a a key to display map with BF1942 back in the day for 2 years...
friends and a good squad is fun with Bf games
lots of rush in BC2
no prone made a massive difference as well
