Age has both its pros and cons for each age group
I am 41 and bought my own TV, Turtle beach, PX21 and DSS I did not need my folks to buy them for me
I am willing to admit there may be flaws in my game play and change mid game or in the lobby for next round to compensate for how the competition is playing
I have more patience in playing and will wait someone out if I get hit moving around map or into room/building (sometimes)
I will not rage quit or dashboard because I am 1 and 6 4 minutes in,  I will tough it out and hope to go 15 and 10 but if I don’t I know the world will not end.
I have slower reflexes but can compensate with my gaming style usually

I have seen too many younger gamers trying to 360 quickscope, drop shot etc whatever the newest fad is in the game. I am too old for fads, yeah I use the FAMAS but I will gun you down on the roof of the truck on grid while you try to 360 quickscope someone at the tunnels. I will shoot you as you 360 jump off the rock on jungle trying for that KEWL utube video to show everyone in your clan
Rage quit/dashboard after trash talking in the lobby and getting your ass handed to you by an old man is immature (but I love doing it)
Yelling at your sister to quit watching justin beber videos because she is hogging the band width, telling your mom you homework is done and you don’t want a sammich or listening to your music/TV way to loud blah blah blah I could go on all day

I play the game for fun, sometimes it’s not fun either due to circumstances beyond my control (lag, hit detection etc) or due to things that are my fault (too many beers, tired after a long day etc) but I am mature enough to suck it up and carry on or just get off line and spend some time with the family

Hate to paint everyone with the same brush but this is more often than not the younger crowd on line but also have play with younger people more mature than some of the older ones I have played against too

or stop playing the game and play golf?

COD elite is coming, to answer the first part.

2nd, there already is a relatively efficient matchmaking system in effect.  When I join a lobby, lets say FFA, I get players of similar skill level.  I win about 1 in 4, and usually rank in the top 3 or 4, KD in the 1's

When I join a friend in session, who rarely plays (and doesn't have much for skills)  his lobby is chock full of greenies.  Went 30-3 on Launch.  27-2 on Hanoi.

I have another friend, who plays alot of TDM, but has a kdr about .7 but is 4th prestige, if I join his game in session again I get matched against weaker players.

The reason this happens is I am obviously bypassing the matchmaking system.
