I happened to mistakenly click a link into the NWN2 forums instead of the NWN2 forums a few minutes ago and came across this gem of a thread started in August 2013 but just updated today titled "Why haven't anyone done a game like NWN since?".
The OP opines that NWN had these critical features:
1: A general purpose roleplaying system integrated in their game mechanics.
2: Toolset and modability support.
3: Multiplayer freedom to DM and host the kind of server for the kind of game you want.
Now it seems to me that NWN2 also has these features. And initially I thought they were going to lump NWN and NWN2 together and talk about why there are no games since NWN2 that have the above features. But no, instead a later post (not the by OP though) says:
I don't want to start an NWN1 vs NWN2 war here but I still think that NWN2 really did more harm than good (out of a multiplayer perspective). It only seemed to lure some wary NWN1 players into trying thoose multiplayer servers only to then drop interest in the NWN series as whole. Sure, thoose players might have been lost anyway...but there was a drop there for no good reason I think.
So what I am saying is NWN2 didn't turn out good. It was not the NWN2 that I wanted and had hoped for.
The thread continues for some time and it is clear that those participating see NWN as an example of all that is wonderful and that NWN2 was somehow a complete bastardization of that. Now while I certainly think that there were questionable decisions made in the implementation of the NWN2 OC, the thread posters are very critical about the NWN OC and do not equate NWN to it - instead they consider the toolset and the community modules to be the real NWN. So considering that the NWN2 toolset is far more capable than that of NWN, you can create far better looking terrains, there are more options that look more professional, all done while still maintaining similarities in conversation structure, scripting, functions, and events, and NWN2 did not lose the multi-player server hosting capabilities of NWN I just don't see what it is that still keeping NWN modders bad-talking NWN2 after all these years.
I can understand if a NWN modder spent hundreds of hours developing a NWN module and then when NWN2 came out became irritated that the NWN2 engine couldn't automatically play his module. But I don't think anyone ever promised backwards compatibility. I was justifiably irritated that a Mac version of the toolset was never released, because they never said that it would be Windows only. But no one promised that NWN2 would play NWN content. And any good modder should have been excited about the more advanced possibilities with a more advanced toolset, not griping and whining for 10+ years.
I can also understand if people invested in establishing NWN PWs and saw the number of their players drop off after NWN2 was released. But they may be assuming that NWN2 siphoned off their players when in fact some probably just moved on. And anyone can set up a NWN2 PW if they wanted to, so it is not like that wasn't a possibility or suddenly became more costly.
So, I just don't understand what the real issue is. Is there something about NWN2 that is so very much worse than NWN that I am missing? Because I just don't see it.
