Well, I have 267 conversations, 2274 scripts, 203 creature blueprints, 728 item blueprints, 26 merchants and 270 areas made for my NWN1 version. Much of it will convert directly to NWN2. Unfortunately, none of the 728 items will. The creatures just need their appearances fixed. And some scripts need to be changed to global from local, but only slowdive can determine which ones he wants global. Mostly areas need to be made painstakingly, as well as creature blueprints for Chapters 3-6 and Epilogue (I haven't gotten them done yet), but certain models would also greatly be appreciated from simple to hard:
For Easthaven and Kuldahar we could use arcane grafitti at ar1014 in Easthaven, a wooden ladder lying on the floor instead of upright, one or two bowls (clean or dirty), a spitoon, a net, the temple exterior and statue inside, mounted illithid, gorgon and invisible stalker heads (empty plaque), a displacer beast rug? (in fact various rugs and paintings), a weird table with blocks at aspel's workshop. In Kuldahar a desk-bookcase, what look's like a cable company spool without the cable (on its side), the staircase for Arundel's place. We could live without most of these things, but the wall writing is very much needed to replace the arcane blackboards and the flat ladder wouldn't hurt (though it is on a stand in AR1011, there are wooden braces for that), and arundel's staircase is really wanted. Dragon's eye has various pools, paintings, banners, pillars, rugs, floor-work and a pyramid. The forgotten temple has lava pools and a unique altar. It also possible some of these are made and I haven't seen them. Only slowdive would know for sure. I'm mostly converting what I have when I have the time, and doing some interiors. I'm bad at exteriors.
I'm sure slowdive has other models he would greatly appreciate that I haven't listed.
