Well, never played Natural Selection, but Battlefield is pretty barren of people with mics. You might hear 1 guy a round with a mic, and Battlefield is screaming for strategizing, and the servers are full of players all the time. Not saying all mods are bad, just the majority. I loved TF for Quake, and a mod called Battle of the Sexes for Q2. Never cared at all for counter-strike. Tried it when it first came out and tried it again a little while ago, and still wasn't into it.
