Sure, but couldn't you just retire the investigators a la Dunwich Horror?
::Laughter:: whoops. I'd completely forgotten about retirement. I almost never get two injuries (I rarely get one) and I don't really like the idea of retirement— it mostly comes into play on the odd occasion when I'm playing with other people and, um, their strategies are... Suboptimal :') I've pretty much retired retirement. I think it's more fun to keep piling madness and injuries on an investigator until they're an insane cripple ;'D My idea of fun is sadism for my imaginary puppets.
Anyways, I retract my previous argument :') except under my house rules (I don't allow voluntary retirements when playing alone, I do allow suicides though :') they seem more in the spirit of Lovecraft).
Bloody FFG keeps stealing my avatars…
