To be briefly pedantic to make a broader point: "One" is an alt limit. Sometimes it's the right limit. I'll agree that often it's not, but there's a Mage game coming up that I believe would only benefit from a one alt limit. Games like BitN are broad enough that I felt comfortable with two, but more felt to me like a grab at numbers. Maybe it works, but it feels like ... whatever the opposite of the fly/sledgehammer analogy is. Smoke and mirrors? Anyhow.
And yes, I'm aware of the abuse of the word "alt" here, as you can't have an singular be an alternative. It's the way this hobby has changed the meaning of the word. Call me Humpty Dumpty.
I'll also agree that if players were responsible for the games they played on, we wouldn't be having these arguments about "what's fine for me is bad for others" (aka "one man's trash"), and even then players would have to be responsible enough to calmly deal with things they disagreed with.
