This is the kind of game I bought a 3DS for. The pop out on the cutscenes is tremendous. It looks like it is coming right out of the screen. If you have not seen it do yourself a favor and check it out (not sure if there are any cutscenes in the demo).
Any other games have great pop out? Heroes of Ruin had a couple of good scenes (thinking of the Goblin King when he is flying around with his helicopter backpack). I wish more developers would utilize this effect. It is awesome.
