I really don't have a strong opinion about 4th, one way or the other. I'm glad that gnomes are gone and that they'll be fixing grapple.
But I think a 4th edition needs to be an overhaul, not a retrofit.
And the covers, while painted well, are boring and the new logo is lackluster for a game with this much history.
But we'll see. I wouldn't expect the gates to rumble when stores open with 4th edition on their shelves.
