"It's a game" is appropriate to use if someone is SERIOUSLy freaking out about actions you're taking, and by seriously freaking out, I mean screaming, swearing, and literally flipping out.
Getting upset at people for ruining experience is not a fair "It's just a game" card. I do it, like I said, with horde mode, L4D, etc.
So I think in the end, we agree.
Simply put - Swiggy, you're right in being upset about mistreatment just because you're not 100% up to speed.
But if you were an asshat going into it, and expressed your "Well I have a life OUTSIDE of the game so I'm not as good as you" mentality, then go fuck yourself.
Agreed?
