Beamdog's remake of the classic RPG arrives on November 28th. With that in mind they've released a trailer to show off some of the improvements. These include: support for widescreen formats and resolutions that were imaginary at the time the game was released, new quests, new characters, and voices for those extras. They've apparently overhauled the original cinematics, and worked up the UI - something that's very obvious in the trailer, below - to make everything a bit slicker now than it was back in the mist of the late 90s.
