Lego Marvel's Avengers Includes Full Story on Vita and 3DS
The Vita and 3DS versions of Lego games quite often differ from the content in the main console version. With Lego Marvel's Avengers on Vita and 3DS though, they will match the console version one to one.
This makes the Vita a great option for children wanting to play on the go without tying up the TV. It's worth noting that the portable versions don't include multiplayer.
