"Is Splinter Cell Conviction a concept and approach to stay or just like a cold, something to get over?"
 
I personally, is still in doubt since I first of all haven't played the finished version of the game except for the easy peasy demo. But I also believe that perhaps they should really consider where they are taking the franchise in terms of it just becoming a failed attempt to conquer a market that only cares about things being the new IN, HOT & quantity, and not being quality? Even though I have the impression that Conviction is a quality game, what will happen to the franchise later on, not to mention their attempts to make it a Spielberg movie?? 
 
I'm confused.... :-S
