I love 2e AS&SH. I’m running a weekly game for two buddies of mine, both DM’s, and it’s awesome. I think the old rules set bothers them from time to time but I’m fine with it, I actually find that to be one of my favorite aspects of the game. And the setting sings to me.
Saying that, I don’t know that I’ll but the new book. For one, shipping to Canada is horrible. Two, I don’t know if I really need whole new classes, especially because so few of the classes from the current edition have been played. And I don’t need a rules update. This edition does what I want it to.
I’ll probably look at the pdf options, in particular the one that focuses on the Hyperborean setting, if that is available.
