The Witcher 2: Assassins of Kings

Simply complete chapter 1

I used IGN's wiki for walkthroughs to every mission/quest in the game
You can skip a lot of the quests your main missions are labeled with a little maker and your side quests dont are blank (You can see this by hitting select and using the triggers to change over to the missions tab)

http://www.ign.com/wikis/witcher-2/Walkthrough

Missions as follows (*** indicate achievement)
-A Rough Landing
-By the Gods - Stringing Up Sods
-The Kayran
-Indecent Proposal *** Man of shadows, Artful Dodger (pt1)
-The Kayran: A Matter of Price
-The Kayran: Ostmurk *** Artful Dodger (pt2), Kayranslayer, Backbone
-The Rose of Remembrance
-Where is Triss Merigold?

At the crossroads is where you decide what path you will choose to take Vernon Roche, decide not to give the sword, or Iorveth, decide to give him the sword

-At a Crossroads: Vernon Roche
-At a Crossroads: Iorveth
-Death to the Traitor!
-The Floating Prison

Side quests (*** indicate achievement)
You will want to complete all of them before meeting Iorveth at the Elven Bath Ruins (assuming you did not follow him immediately after the Arachas battle)
Some quests don't go away as they are ongoing throughout the chapters
I Highly recommend playing all of the side quest so that you can reach level 35 and also because it adds to the story :D
