It seems people who play a certain way, or people with certain personalities, play as certain characters. May it be a COG or Locust Character.
Gears of War 3 introduces DOZENS of new characters, allowing people to choose over many different personalities of characters. From my analysis, here is what I found:
(IMPORTANT NOTE: This is NOT to discriminate ANYONE. This is just the majority of average players. I have owned, and have been owned by all of the possible characters in Gears 3. Apologies to anyone offended.)
I use Classic Marcus and Grenadier
*ADDED CONTENT 2/5/12
-individual classic characters
Marcus - Noob, or a player who joined a Quick Match, pissed because he wants his default character.
Dom - No one uses Dom. :/
Cole - The second you go down, he's right there to tbag you, then punch you in the face ten times.
Baird - Technical player, utilizes use of all weapons
Anya - Sawed Off HOAR.
Sam - See above. But instead, will wallbounce with the Sawed Off instead of Rush
Unarmored Marcus - Little kid half the time.
Clayton Carmine - Usually a little kid. Other times just someone who goes 0 and 10+.
Benjamin Carmine - Varies. I see Ben players go neutral. (Same kills, same deaths). Weilds Sawed Off and Retro
Anthony Carmine - Proud vet of Gears of War 1 and Rank 75, always hogging the sniper
Classic Marcus - Picks him because no one else uses him
Classic Dom - strafers. and damn good at them
Classic Cole - See "Cole"
Classic Baird - Good players
Commando Dom - Always goes in first. Hard to hit, so wallbounces and strafes alot. Gets killed by frags everytime though.
Mechanic Baird - Always has snipe or torque. Misses half the time
Adam Fenix - I find Adams to hog frags. I dont see him too much
Civilian Anya - A wallbouncer, who uses her because she is so hard to hit.
Barrick - Aggressive players. Often seen going in first, or Retro charging.
Kim - Professional Gears of War player
Valera - Usually an advanced player.
Tai - little kid. but I usually don't see him too often.
Griffin - Gangsta straight outta Compton, Iced-T fan, or common American white male.
Jace - rarely seen, but a support player who does his dues.
Superstar Cole - Gloating player who trash talks.
Cole Train - "I played the Beta!!"
Bernie - kills you 3 times in a row
Hoffman - thinks he's the leader. Rushes in first.
Prescott - Plays this game too much. Usually good player
COG Gear - Noob
Onyx Guard - that annoying power weapon hogger who gets killed in every 1 on 1 situation. Usually kills you from behind
Dizzy - He's all over the place. Bad, and good players use him.
Golden Gear - 1500 points. All damage points.
Drone - Joined a QM and is forced to be the drone
Sniper - Hogs the snipe, but knows how to use the shotty
RAAM - noob
Grenadier/Elite - Shotty 2 your body
Kantus - Has a power pistol (boltok usually), and a grenade hog. ironically, never revives you
