I have to agree with Mr. Cashel, but then again, I'm an editor, too.
I think that there are at least 2 reasons for poor-quality editing in a big-cost production, like a nice core book (or core books)
* A lack of a genuinely fresh pair of eyes reviewing the work. I know that after reading & rereading someting for lord knows how long, some errors are going to slip through the cracks. This is especially true if the editorial dept. of the company is severely understaffed &/or overworked.
* There's a good amount of pressure from the higher-ups in the company to meet a particular publication date, especially if there's a lot of fanfare about the product's release. This could be fine & dandy if things go well, but more likely than not, there'll be delays occuring somewhere in the system--either the authors/editors/artists/people working on the project aren't delivering their workload on time, or there's an issue that causes a setback for the product, bringing about a good amount of rework. Then again, the product could simply require more time to work on than initially envisioned, but the higher-ups aren't very willing to push back the schedule (& thus, pub date) to accomodate this.
I'm very sure there's a lot more reasons why, but these are the first 2 that come to mind. It can be very frustrating for an editor, whose job is to ensure the best quality product possible, to be told to meet quick-approaching deadlines with limited resources and time split amongst several projects. It's even worse when the editorial dept. is understaffed, because that's less people able to contribute time & effort on the product, as well as provide a fresh new perspective that may catch things that the primary editor may have missed in the midst of rewrites, revisions, various versions of different chapters, etc.
As much as I'm interested in the Lord of the Rings RPG, I was a bit hesitant about getting the game (my group really isn't that keen on LotR, esp. after any experience with MERP). After hearing about poor organization and quality issues regarding the book, I'm glad I didn't purchase it at all. Along the same lines, I bought the Marvel Universe RPG only to be disappointed by the inconsistencies within the text. Quality counts, especially when it's for a bound, published, on-the-shelves product that people are paying good money for (don't get me wrong--electronic, online resources should hav ehte same level of quality, but at least an online resource can be easily pulled at the last minute for edits, compared to the very costly action stopping a print run of a book).
So there's my vote--quality counts. I think it's very important--so important that I urge people to "vote" with their buying power, purchasing only products that they want that are of high quality. If the quality's low, then let the sales dwindle away. I'm sure the people who actually physically worked on the product know this, but it's equally important to show the people primarily involved in sales & revenue the impact that poor worksmanship, especially due to poor business planning, has on the bottom line.
Sorry about that--didn't mean to get too preachy, but it's something that's near & dear to my heart (heck, it's my livelihood!). You should see me when it comes to issues of censorship, consistency in writing, & the issues of canon works!
Mind you, I'm sure there are a few errors in this little post right here, but then again, it's a low-budget work with a rushed publication date.
