Midville: Thanks! I'm going to have to give this edition some serious consideration, then.
It'll be, what, the fifth time I've bought Neverwinter Nights? But worth it, especially if the game is spurring the creation of new PWs and such. As seems to be the case.
What I'd really like to see is a Mac-compatible toolset. If that were included, I'd buy it yesterday!
The Enhanced Edition is the 3rd time I've purchased the game, and the reason I purchased it, was for the native Linux version. I have the original running on Linux, but it depends on 3rd party community hacks for the videos to work. The DLC content was the other reason I purchased it. I never played most of the modules when they were working with the original. I have been very disappointed with the cutscene videos in the Enhanced Edition though. Beamdog re-encoded all of the cutscene videos to webm format, which was fine, but they lowered the resolution on the videos from their original 800x600, down to 660x600, which also makes them an improper aspect ratio and gives them a horizontally smashed appearance. They aren't scaled either, so they play as small, smashed cutscenes in game. I had to re-encode all of them myself, from the original bink videos out of the Diamond Edition. They at least look proper now, with their original resolution and aspect ratio, but they still aren't scaled in game and I really shouldn't have to do that with an "enhanced" edition. There is no option to change the game resolution in-game either, unlike the original. I have no reason to change it myself, and it can be changed from the .ini file if I needed to, but it seems odd that they broke that functionality and left it unfixed.
The rest of the game however, is exactly the same as the Diamond Edition, minus the DLC content, unless you get the Deluxe version. There are a couple of extra shader effects, but I really can't tell the difference when comparing the two or toggling them on or off, so I'm not even convinced they are working. I can also say that the Linux version doesn't come with anything more than what the original came with, so there is no toolkit either. I would suspect that the Mac version would be the same case. It possible they could always release it at some point in the future, though I wouldn't count on it. I tested the game itself with wine-staging 3.18 and it ran flawlessly, unlike the Diamond edition, so you can probably run the Windows version of the toolkit with wine as well. It's not ideal, but it is probably an option at least.
I'm guessing the game will probably further improve with time (thought the game has been out since March 2018 now). However, as it stands right now, there really isn't much to be gained over the original at this point, unless you want multiplayer or plan on getting the DLC content, or unless you don't already have a native Mac edition. It's still Neverwinter Nights, and it's a great game, just make sure you manage your expectations of what you are getting with the "enhanced" edition, since there is really only a very small difference at this point in time, from the Platinum Edition, or the Diamond Edition if you are getting the Deluxe Enhanced Edition of the game.
