If CGI were to upgrade HM Religion, Magic, etc, to HM3, it would derail all other CGI Harn publication for two years at least. Every time you open a project, you have to go through it carefully for additional errors. All the writers/reviewers in CGI's stable are volunteers with day jobs.
You are free to use HMC with HMM, HMR, etc, if you prefer those rules, just like some people use HMG or even HM1.
Knowing the CGI people, if they were to update those books to suite HM3, then they might as well bring everything to HM4. That would take a long time indeed!
HarnWorld and HM are very rich, permitting levels of character-setting interaction not seen in all games. This requires a certain amount of GM judgment. It is always a challenge findng the line between content and constraint.
I'm sorry if those issues are a stopper for you. We don't see an awful lot of complaints about it, as you have discovered:
I did post a topic months ago, and it addressed the topic, but nothing concrete came from it.
It took me about a day to found the most basic "bugs" and write my own errata list so please don't exaggerate.
As it was mentioned in another thread with similar title, I sent an email about the the most basic of the most basic bugs (yes the word basic is used twice). Krazma sent me an email that he was doing something (I don't understood what, but he answered so I guess it was about my complains). Also as I mentioned in the other thread (why having two threads?) and in my email to CGI. I was most irritated that the "bugs" was even in the new articles.
I am aware that the ones who writes for Hârn sometimes don't even play, they play with another system, or with older rules but the most basic rule when you are writing official materials is to stick to canon and to the system not to some older rule that you remember or some houserule that you have but no one else.
I own everything Hârnic so I can (also mentioned in the other thread) backtrack and see on what rule-level the writer has stuck on and where he did go wrong. But newbies can't do this and everyone does not have all the rulebooks so they can backtrack and see what the ... is wrong with this, everyone perhaps can't afford to buy all the rulebooks that has ever been so they know what to do.
A simple solution, done by many other game companies over the years is to send an errata list on what the differences is with the new rulebooks so anyone that happens to stumble accross old materials knows what to do. HM3 could have done this and partially they have, but here they have also done a big mistake, the religion and magic parts of the HM3 rulebook are just copied from the religion and magic modules and they are not up to date.
And also as we have already discussed to the Nth dimension and back, this is perhaps not the biggest issues in the world, but still it took me a day, sorry I may have exaggerated saying that, two days to correct the most obvious issues.
