I personally despise NWN2 it is one of the many things that obsidian has ruined, fallout in there aswell. if you're agonising over which toolset to use, remember, your creation on either won't be a game, simply a mod or campaign for an existing game. If you wish to make your own, try learning java or emailing Iron Genesis to ask if they need some help with their first game. If i recall correctly, Iron Genesis's e-mail is contact@gameitgames.com and their website is gameitgames.com Have fun and let me know if you choose to go to Iron Genesis... I wanna know what they're like.
