Depends, If it's a game series I trust like AC, uncharted, inFamous, etc then yeah it will make me want. But mostly I like to see how it plays since it's game. I don't want to see a cinematic because I am not buying a movie, I'm buying a game so I want to see how well the actual game is (which is hopefully what they did the most work on) instead of how impressive the cutscences are. Any game can have nice looking cutscences but not every game has good gameplay.
