No, Witcher 2's trap system is not going to be like Skyrim's trap system. Witcher 2 is a bad game. Skyrim is a good game. Completely opposite. But, yes, there are going to be traps.
Witcher 2 is an RPG that makes pretty much every other one on the market look absolutely pathetic in terms of writing, dialogue, graphics, themes, characterization, quest design, and choices and consequences. Combat's a bit clunky but I can live with that. And Skyrim is not a good game right now because it's not out yet. It
will be a good game once it's complete, at least I hope so.
