No one has said that playing the campaign the way you have is "just glitching it out", so there isn't much point in tearing down that strawman. I did watch the video, BTW, and think that it takes a lot of practice and talent to play that way. I didn't mean to diminish what you had done. I have a pretty solid knowledge of NWN and have played the OC several times. I saw you do things I didn't know could be done and that I certainly couldn't do without a lot of skill-building, and maybe never as quickly as you did them.
Of course, the run did use exploits to get the job done. I will agree that it is often difficult to determine the developers' intent. However, let's not pretend we think they intended that you could slip through plot doors, duplicate plot items, or gain several hundred thousand XP by repeating quest completion in pause mode. That does not mean that doing those things was easy, just that they are exploits. Plenty of exploits require skill and cleverness to make work. If that's the way speedrunning is done, then I have no issue with it. But, you have to expect that people in a forum where most don't do speed runs will tend to think of those techniques in the context that they are more familiar with.
By the same token, using the console to go through a whole campaign wouldn't exactly be a skill-free endeavor, either. Without practice (and without using some of the exploits you used), I doubt that most players could start in the Prelude and get through the whole OC using the console in under 40 minutes. Certainly, they aren't likely to be able to do it without going outside the game to generate a list of spawnable plot items and area tags, at least.
(BTW, as a side note, I think it's entirely possible that BW did intend monk speed to stack with other speed increase effects. I don't know that they intended it to stack quite as well as it does... But, it's certainly reasonable to think that they knew that it was happening well before the 1.69 patch and never got rid of it.)
Anyway, I enjoyed the video and I am glad you posted it. Even if I never speed run, I learned a thing or two.
