Such "line work" can significantly influence the quality of games. I hope they take the time they need.
After not touching it for about a year I'm back in the Witcher 2 to finally get Act 1 done and work towards finishing the game.
The Witcher games are awesome. I'm a huge fan. They have a level of maturity that I miss in other role playing games (although Dragon Age and Skyrim are very good games, too). But The Witcher games feature a dirtier world and therefore the player is often put in a position where he can only choose between the lesser of two evils. Also, the plot changes based on the players choices to such an extent that you get different levels to play. I hope you enjoy it.
