It is official from Bioware that 1.68 will be the last patch.
I know that at the moment, I'm not really keen on NWN2 for a PW community. I expect that until March/July '07 it won't really be feasible to even have something high quality up (suspicion only but it grows stronger the more I hear).
Which means that by this point, new players aren't really going to be coming to PWs. The community as it exists now, is more or less all there is. New players are unlikely to pick up any more additions of NWN in stores and start fresh. Those people we have are likely already pretty 'hard core' about this hobby.
Which brings me to my point, knowing nothing new is coming out of Bioware after the next patch. How many people still object to .haks for new custom content?
I know some of the objections: "I don't want to spend the time downloading them!" to which I reply "Well, you spent hours and hours downloading patches already to play. There isn't much difference."
"New players won't find us as easily to join!" Reply, "What new players, by the post-1.68 stage new players won't be picking up the game. Anyone still around this long is die-hard enough to download a .hak if you make it easy."
