One of the things that irks me about 4E is what I view as an excessive focus on the game qua game, to the detriment of simulation; yet the quality of the game aspect is also one of 4E's great strengths for me. I want it nudged a bit toward simulation and drama, not yanked way across the room.
If I understand GNS right, 4E would be heavily "simulationist" as it uses the term; its design goal is to simulate cinematic combat and (through its skill challenge system) cinematic dramatic situations (though it is still a bit underdeveloped on the last point just yet). "Gamism" as GNS uses it is about actually balancing players against each other so that they can be challenged in game. Magic the Gathering strikes me as more of an example (though not an RPG) of this.
