My favorite thing about TF2 is how when it comes down to it, the characters are all psychopathic, mentally deranged mercenaries wasting their lives for hats. Like even Ms Pauling is a workaholic secretary who’s also basically a serial killer. As comedic as the premise is, it’s also dark which is fitting for Source engine games.
Every other game makes their characters noble heroes saving the world from armageddon which is overplayed. The TF2 mercs go against machines, but it’s not the main game lol
