Lego City Undercover - the Chase Begins had breaks and loading screens or no? I forget, it's been a while since I touched the 3DS version. I am not sure, seems maybe their engine is less taxing and has better feature support.
I'll admit, I haven't actually started The Chase Begins yet (Though I do own it), but the loading can get pretty bad in the Wii U version and I heard worse rumors for the 3DS version.
