Another trailer that is nearly void of actual dialogue and from the first frame establishes everything we need to know about this world.
While many who played the first Witcher knew the quasi-medieval universe they were about to inhabit in the Witcher 2, many first timers were presented with a complete picture in less than five minutes. Magic, royal assassination, swords, and political intrigue are all firmly established without an appearance by the protagonist or a single piece of exposition. Watch this more than once. Trust.
