So just about every mod they make minor modifications, and changes in difficulty to old stuff that we have run 2000 times. I have to confess it didn't make my 2001st time any more enjoyable. For example: Really does anyone give a wet fart if someone who piked picked up a set of Ventilated Bracers???
And NPE? Sure do something for new players. Where are all these new players comong from then? You can't find a single GD box on the shelf of any gamestore, Target, Walmart, or electronics supercenter in town! But small thanks for making the next 2 hours of the next time we level something interesting I guess.
My suggestion:
Make a new raid, playable race, class, spells, feats, monsters, PrC/enhancements for classes that don't have them. Basically the stuff we hound you for day in and day out on the forums. Keep existing players happy.
If you want to reach new players you will have to put a new package on the shelves (if you can even find the old one it is a smashed up copy on the bottom of the bargain bin). Online ads or articles linking to the trial wont work, do you have any idea how many of these types of ads gamers come across in a couple minutes of websurfing??? Too many to trial them all that's for sure.
