Why I'm anticipating The Witcher 2

I stumbled upon a recent trailer for The Witcher 2 (sadly, NSFW so it can't be linked to) that made my anticipation for this game increase exponentially. In one scene during a prison break, the player is able to talk to a man who requests that he be freed. If the player refuses him, the prisoner will call for guards. Normally, this wouldn't excite me except for the fact that the player is able to hide before the guards arrive which will cause them to beat the prisoner for causing a distraction and allow the player to escape unscathed. This is beyond brilliant to me since I haven't seen gameplay scripting this amazing since Deus Ex or quite possibly even Fallout 2. The Witcher 2 may just be the kick in the pants that the industry needs after years of excessive gameplay streamlining. The Witcher 2 seems like it'll be the type of game that'll give players many subtle options that the player didn't even know existed. Assuming that the game manages to live up to the hype, it will either be a great title that shows what gaming as a medium is capable or it will be the evolution of gaming as we know it.
