Been hearing an argument that there's never been such thing as teamwork in TF2, and that absolutely no one who's ever done anything for charity involving the game (ie. buying the Japan disaster relief hats) gives a flying shit about it, they only want hats and attention.
"To a selfish man, every man is selfish."
That is to say, I call bullshit.
I'm one of the people who started playing the game when it went free. And guess what? Even before I learned to play the game properly, back when I still utterly sucked and was nothing but a dead weight for my team, everybody was still nice to me.
I openly admitted that I was a rookie, and apologized for being unable to help, or even for making things worse (for example, I had yet to learn that burning Medics ALWAYS have dibs on medkits), and asked the other players for tips.
Each and every one of them was kind and polite to me, saying that it didn't really matter if I messed up because it was just a game so I should cheer up, and gave me useful advice that helped me a lot. One person even gave me a weapon as a good luck gift.
And before anybody says "LOL it's because they are all virgins who are desperate to impress a girl!", I always play with a gender-neutral nickname and without a mic, they had no way of knowing I was a woman.
Have I also met some douchebags since then? Of course. In the many months since I got the game, I've been playing and trading for hundreds of hours, meeting countless different people. It was statistically impossible for all of them to be nice. But, in my experience, the majority of TF2 players are friendly and patient. It's NOTHING like Call Of Duty, the attitude is completely different.
Sure, a lot of the time the players act as if it were a single-player game, with very little unit cohesion. But I find that usually it's not really selfishness, it's just ignorance. For example, many Pyro players simply don't know that they can extinguish fellow players.
The tutorials are rather shallow, and a lot of things are never explained in-game (for example, one of Spy's main techniques, the stab-and-sap maneuver, is never even mentioned in-game, I only learned of it because I went out of my way to check several different strategy guides. We are not talking about an obscure trick here, we are talking about a technique that is pretty damn necessary for taking out sentries, which is one of Spy's most important objectives). It's not really the players' fault if they have no clue how to act like a choesive unit.
Tl;Dr: The TF2 Fandom is cool.
