Mechanically BF2 is the most fast paced of all.It’s kind of like counter strike with iron sights.I used to instantly dive and headshot people.BF4 is more random,with slower aiming and less skill based gunfights,but the maps are more tightly designed so it’s a spamfest
always. map design has been the series achilles heal.
It was atrocious in BF 2 because it basically forced vehicle play out of necessity. in BF3/4 there were a couple good ones but that game’s failure was in faulty flag design, BC2 maps were imo the best in the sense that they were designed well for their respective modes ( having separate maps for rush and conquest was still the best decision DICE ever made) and were well designed for the player count, but they were overall pretty bland and very much stuck in one level with little verticality.
