Not...exactly. See, I won't be tracking it. I also don't railroad people. If you decide to do some side quest, or go off in a direction I don't expect you to, you very well might gain 2-3 xp for it. Or it might be a dead end with nothing worthwhile. We'll know when we get there. The game will be distinctly non-linear, and player driven. Yes, I'll have events happen. But if they happen, players are perfectly in their rights to ignore those events. Oh, the consequences, what there are, will still happen. But I'm not going to railroad you into it. Thus, 'speed of plot' isn't exactly the right term. I don't know what is, though. I'm seeing it as closer to the Milestones that are awarded in the Dresden RPG.
