Been playing this game for 5 years. I don't need to say anything else about it.

Update:
Just nominated TF2 for the “Test of Time” award. What can I say, still the third most popular game on Steam, after being out for 9 years. Easily my most played computer game ever. Nothing quite like coming home from a stressful day at work and burning a capping scout, or head-shotting a heavy from across the map. Just makes life seem a little bit more peaceful.
Continious updates bring additional content without impacting core gameplay. Valve had a genious idea when they targeted a cartoonish, think Wile E. Coyote, feel for the game. It has made the graphics look as in place today as the day it was released, while all of the games from 2007 that went for a realistic feel look seriously dated.
Of the nealry 400 games in my library, this one keeps me coming back.

Update:
Make that a full decade of TF2, now with Jungle Inferno!!! Nice update that changes the way missions are handled in a much better format. Well worth the free download, even if you don't like hats.

Update:
I've played a bit of Fortnite and while I understand the appeal, there is nothing quite like getting back into TF2. The damage you can withstand is a lot more and it creates a much different dynamic.
