I think being able to run a plot arc from 1st to 30th, keeping the PCs interested and challenged the entire time, and have one of the major villains be someone who's been along for the entire ride, is one of the Holy Grails of DMing.
Well, that's the point - he
plans it, but if he can pull it off, it's more due to his DMing skills to keep the PCs interested.
Looking at his campaign outline, it looks like it's very narrowly focused, at least geographically. While it's certainly possible to confine yourself to such a small area, it can keep it a bit "stale". Sure, if your players are happy with being centred on this, sure - but this may not appeal to all players - for example, my players enjoy the "sightseeing" of Eberron - visiting the jungles of Xen'drik, passing through the Mournland, occasional intrigue in Sharn - stuff like this can generate a sense of adventure (depending on how you present it) and gives you an interesting range of backdrops for battles.
Keeping yourself restrained to rural sceneries
can make it boring - and make it harder for DMs without good DMing skills (it's a bit like special effects in movies - depending on your players, pretty handouts with pictures of the new region can help them to ignore plot kinks and other faults).
Not saying that James cannot pull this off, but things like that are certainly dependent on your players. And as this is an article to help DMs, it may be worth pointing this out.
Cheers, LT.
