I agree with naidel, you are on the right path, but are drawing a flawed conclusion from your experience. It seems your other players had experience playing RPGs other than NWN, if you had played any other RPGs you should know that if you don't immediately kill something it's likely to kill you the moment you get too close, or you say the wrong thing, or a cut scene happens, etc. There are also many things RPGs have done to "dull the senses" as it were, such as the chittering sound. Play ANY modern MMO and you will find yourself assaulted by sounds relative to the area you are in, making any background noise non-substational to play style.
The most glaring problem however, seems to be that you didn't bother to test your module. A simple 5 minute run through your module would have been sufficient to determine whether your beetles endlessly spawned. You put deer in a forest without expecting a player to try and kill one? While immersive, in computer games everything is possible symbolic and will likely be summarily killed to see if it triggers anything else.
Honestly, all in all, it seems you were unwillingly to compromise your "vision" much like EQ was a few years back. They had this great plan of pulling players into this immersive world and were upset when people micro managed and beat the crap out of it (the other way your modules could've gone). NWN, like many games, does not have a "oh I was just kidding, I didn't really mean to do that" button, nor does it have the limited input of whatever the GM tells you, hence, games lead to chaotic instances all the time because players are not shown the way (i.e. obvious hints to continue storyline or show possible side routes were missing).
Your heart seems to be in the right place but it doesn't sound like you had the effort put into learning your environment before you jumped in head first. I realize 20-30 hours might seem like a lot to you but for a fully tested, bug free experience you'll need more than that...or you'll need someone elses modules.
