This thread is quickly turning into a one-man show, here.
So, I recently found this page: RogueDao Studios
-- these people are apparently using the NWN2 toolset to construct a new Planescape Trilogy... it looks like they've been working on it for quite some time, now, but I find it very interesting. They've got screenshots and all... .
...Not sure how they plan on paying for all their time and effort and other expenses, using a toolset owned by another company... I suppose we shall see.
I've got the 1.0 version of Planescape ("new" aka "unopened" (supposedly)) . . . but it's not the 4-disk version, nor is it the 2-disk version, it's only 1 disk incorporating everything... so since a number of the fixpacks mention whether or not to apply the fixpack depending on whether you have the 4-disk or 2-disk version (the 2-disk being already updated, supposedly) : I'm alittle annoyed that it says nothing about my 1-disk version.
I was able to install the "official 1.1 patch" fine, of course, since that was self-installing . . . and installing one of the fixpacks (forget which one . . . Qwinn's I think) was easy, since it just required replacing a number of the files in the Override folder (after, of course, duplicating the original folder "just in case") . . . with Qwinn & co's additional v4.0 fixpack, I'm still trying to figure out what to do with the files... it looks like a big, annoying job to me. Somehow I doubt the game is going to recognize the separate folders that Qwinn's new fixpack supplies, since the game doesn't contain any folders, as it is, with colorful titles... which means I have to copy all of these files into some folder(s)... I just have to figure out which one(s). The sound files (Mortai's interjections) are maybe a little more of a puzzle as to where I'm supposed to put them. The Override folder, again?
(sorry if I can't give you the websites I got them off of -- I'll have to go back to the BootCamp partition and get a hold of them, then put up a post listing them . . . . but any web-search should find them for you. Sorcerer's Place has lead to at least one of them, anyhow.
I'm particularly interested in the Banter files, though... because I love banter! In-party banter is one of the things that made NWN2 NWN2.
