Overall this is a great addition to Arkham Horror and every other expansion set they've ever made.  It's basically just more cards for everything.  I understand that with the big board expansions (Innsmouth, Dunwich & Kingsport) Miskatonic actually increases the odds of drawing an open gate at these boards.  That's good news as the biggest problem with those boards is that you could have potentially finished a whole game without ever visiting those boards.  Um, this comment is for all you veterans.
