I'll say something nice. I was originally very suspicious of the announced changes in 7th edition, but once I got the PDF rulebook and started going through it, I found that I ended up liking just about every change. My group and I switched over from 5.5/6th edition (though we were already using the "push" and spending-Luck rules) a few sessions ago, and all the comments I've heard about the new edition have been positive; my players really like the bonus/penalty dice, the degrees of success, and the revised combat system, and I'm really enjoying running the game. The nicest thing I can say is that despite all these changes, it still feels to me like Sandy's original Call of Cthulhu; the changes are procedural, not tonal.
