I'll keep this short and sweet, as I've been up for ? days. Maybe only the, from the very beginning, real old-timers, will get this. There are RPGs,and there is D and D. 4e has managed to combine the spirit of the old, (archetypal/niche/team dynamic) and the methods of the new.
D and D (the real :) version, the original) was never meant to be all things to all people. The characters had very specific functions roughly correlating with archetypes and dramatic functions. The characters were never meant to be all things either.
I would say in this version, there are a variety of ways to be that type, as opposed to trying to do and be everything, ending up in a pen and paper arms race, with the Lords of Marketing cackling and rubbing their hands.
Skills, much simpler. (you either have it, or you don't, though you can still roll) Feats, while never my fave in any version, don't seem to be so much of a sales gimic/munchkin bait. Maybe WOTC learned you can make money without resorting to manipulation. I hope so. Great job in this case so far.
I have never had much good to say about this company, but that seems to be changing.
Very, very well done. If you sold me, that is no mean 'feat'.
Really, and I know I'm in the vast minority, still. Please keep it up, I mean quality, not gimmicks. Really. I think Mr. G would be most pleased, and I really hope that matters to people.
Oh, the art? I never really cared, I'd call it high quality illustration. I'm purely pdf. I don't know how it prints, and I likely will never find out.
Hope this helps. Nothing is perfect, and a five has to be there for a reason so here goes.
