Well, since you all at Paizo asked for our input on this game, here's mine. I'm like Forsetti, a D&D player from the '70s. I remember the old AD&D rules for max & min values for PC's...they made sense. A halfling with a 20 Str was and is ridiculous to me. I have an in-house set of rules (which are just a copy of the old 1st ed rules) about max natural ability scores. And please recognize this, I have problems with the base, natural score being too high or too low for a non-human race. So, I'd like to see a little bit of change in that direction.
Also, I liked having the "cartoons" in the old books because they were funny AND they taught the rule in a way which was easily remembered. A few cartoons to illustrate some of the rules would be nice. But they should be multi-panel comic strips, just one panel chuckles.
Lastly, a couple of interesting bits of art or samples of play to help new players get the feel of the game. I know that if I mention Emirikol the Chaotic, a batch of you will remember Dave Trampier's full page art from the 1e AD&D DMG. And the script of game play I've used ever since when trying to describe to someone what a game is like. It works. We've got lots of podcasts out there. Find a good one and put in part of the transcript.
Well, that's my 2cents....back to hiding in the dark....
