I'm surprised there isnt a kickstarter project already in the works for a Neverwinter Nights reboot.
One thing I'd suggest is that the game must NOT rely upon any centralised hub or server for any of its advertised gaming abilities.
Eg: No master server.
TBH - There are some interesting things happening in the bitcoin and namecoin development from the aspect of decentralised data.
Bitcoin and Namecoin do not use central servers, they use peers to hold the information.
The only way to successfully launch an attack on the network would be to control 51% of the peers.
A master server functionality built into a decentralised peer network could theoretically work, and would become more secure as the game becomes more popular.
