I don't think chargen needs to be mandatory. Have the set be the same and mark the chargen as optional or to be read after initially playing.
So your thing, though, is that that needs to be printed, and included in the box. The extended online options being guessed at are not enough. Is that right?
This discussion puts me in mind of an experiment that I could possibly run. Quick background: I started playing in '78 with Basic, got the Advanced books later but I really wouldn't say that we were playing AD&D. Continued playing using B/X and BECMI through part of the 80s, then pretty much left the hobby. Came back out of interest in 4E, but it didn't do much for me. Since I'd skipped the whole 3.x/D20 era, I thought I should check that out. Bought the 3.5 Player's Handbook and was completely overwhelmed. Interesting reading, but I didn't want to play that game and, by extension, Pathfinder. Spent the past few years playing D&D mostly through retroclones and my old materials.
But a few months ago, I bought the Pathfinder Beginner Box, because I love boxes, because I'm old.
Haven't done a thing with it. So despite my role-playing background and some familiarity with the systems recent years, it's all pretty much new to me. If I were to open that Beginner Box, I genuinely wonder how long it would take me to digest it, get 3 or 4 friends who were completely new to it, and run it (chargen and all) RAW. Would we get to the adventure the first night? Would they have fun diving in through the rules review process and building their own characters, even if it took an hour or more (would it?). It would be really interesting to stopwatch all the steps and judge everyone's reactions. If I were really ambitious (and had more close friends), I would even repeat the experiment, but this time let the players choose from a small stack of pregens, and dive right into the adventure.
It would be an interesting way to kill time between now and July. Except I think I'm more interested in saving it for the D&D Starter Set, and I really only have so many friends.
