Aspyr, maker of many Mac game ports, has confirmed they're working on a port of Neverwinter Nights 2 for the Mac. The game features straight-up D&D action in the Forgotten Realms setting, and while not quite as critically acclaimed as Neverwinter Nights (that one was made by Bioware, after all), it did grab a pretty respectable rating of 82 over on Metacritic.
There is one problem-- the toolset that players can use to create their own content which came with the PC version won't actually be ported to Mac (more evidence that we're getting leftovers). Those of us who buy NWN2 on the Mac will still be able to play that created content, and join up to all the persistent world servers players have put together (and some of that stuff is pretty cool). No release date yet, but we'll keep you posted.
