fronzelneekburm: Not at all. It definitely is a dick move using community created content without giving proper credit. However, having the game pulled altogether isn't exactly the most desirable outcome. I've paid a quick visit to the fan forum in question and was a bit bewildered by the self-congratulatory tone of its users at having the game removed from circulation (thus my rather dismissive wording - I'm sorry if I stepped on anyone's toes. I can't claim to know nearly enough about the facts of the case to make any kind of objective claim). What if the Korean IP-holder can't be bothered to supply gog with a non-modified version or a deal of some other kind can be struck? What would that achieve other than the very game they have been keeping alive for 15 years going right back into obscurity?
While having the game pulled isn't the most desirable outcome, keeping it available non-modified is, IMHO, not a the way to go either, just for the sake of keeping it available.
If the Korean IP-holders can't be
bothered to supply GOG with a modified version, then they shouldn't be making any money from it.
If they can't make a patch of their own but also can't be
bothered to offer the unpatched/ original version, then they shouldn't be making any money from it.
If they can't co-operate and credit the modding community but still want to use their efforts, then they shouldn't be making any money from it.
Why? Because it sends the wrong message that pubs/ rights holders can trample over anybody as long as they end up with a profitable (patched/ better/ etc.) product.
And yes, I read some of the posts on the fan forum, and yes there are some worrying signs of "IP ownership" by the fans. I was as much surprised and baffled by the intensity of their stance as the next person. That doesn't change the fact that they're in the right in this specific matter.
At this point, the only viable solution I see is for IP holder to release the original version as it seems unlikely that they're going to reach an agreement any time soon.
EDIT 2: Oh boy! Thanks to Gydion providing the link to the discussion I mentioned in my first edit, I've now read the latest developments of this story. Given that:
-- the community patch was made using the source code of an unreleased Xbox port that was obtained under unclear conditions, and
-- with the names of MS popping-up in relation to the development of that port,
I firmly believe that GOG did the right thing to pull the game. Even if the IP holder and the community come to an agreement regarding the use of the patch in the official release of the game, the best course for GOG would be to stay clear of it - the legal uncertainty is too high to take a risk, unless they also own the rights to the source code for the cancelled Xbox port, which sounds quite unlikely though.
So basically regarding GOG, the best course is to release whatever version is regarded as the latest official one by the previous rights holder (Throwback Entertainment). Unless the current one comes up with their own patch based on the source code they do have legal rights to.
EDIT: Just to add that we've derailed this threat enough, I think. IIRC, there's another discussion going on regarding this matter, but I can't find the link to it now.
