Projectsonic: But either way that means everyone is going to jump at the chance to make more NWN stuff again. We could have a real renaissance here either way
I've seen this argument mentioned several times now, and while I can sympathize with it and really hope that I'm proven wrong, to me it just sounds like wishful thinking. It's still the same game, the same graphics, the same appeal; it was available before and everyone wanting to make more NWN stuff was able to do so already, but very few still do these days. The EE won't make it much easier to create your own content, and I doubt it will suddenly inspire many people that weren't into creating their own content for a 2002 game before.
I had similar hopes, when Forgotten Realms Unlimited Adventures (FRUA) was released here on GOG, and yes, it's even older than NWN, but it was actually unavailable before in a legal way, and I thought many people weren't aware of the game and what you can do with it yet, contrary to NWN. Also, it's much easier to create your own adventures in FRUA. I don't think a single new module has been created by new players since then, and the community boards hardly got any new active members either.
I also had such hopes whenever a new RPG was released with a campaign editor (e.g. Dragon Age: Origins, Driftmoon, Shadowrun series, Divinity: Original Sin etc.). They never developed significant communities in the first place and never had a significant amount of real quality content created for them. It's just not something you can take for granted, that people will get creative, just because a game gives them the tools to be so. And the EE hardly offers anything new to inspire them (just look at what awesome, beautiful and inspiring custom content was created for NWN over the last years by some die-hard modders - if that didn't manage to make more people want to create their own modules, why would a few GUI fixes and adding shaders achieve that?).
