Graphics:
From a Lego game you should not expect much graphically simple, that's a fact. But it still looks very good, and in some places the game looks so vivid that you feel to see real Lego. A graphic bomb should nevertheless not be expected, but should not underestimate you look at it.
Sound:
The speakers are amazing, especially when you consider that you have about 100 Marvel characters in the game and each one speaks somewhere sometime. All voices fit the characters. The music is very consistent and fits the circumstances.
Gameplay:
Here I was surprised at most of the game. I initially only one level after another played until I strapped that when you're in New York between levels, it is a completely walkable large city, with side missions and all the trimmings. There are escort missions, racing (car or fly) fights, etc. One can freely play or steal vehicles as well as in GTA. Simple triangle button and the hero jumps into the car. The driver will not get dragged and beaten as in GTA, but he leaves the vehicle voluntarily to the hero, and then says something like "Sure, superheroes use, I understand, please take my car." So very family friendly the whole. The sheer number of characters and vehicles that you can freely play is huge and busy one for quite a while. It is also not too hard in this game to unlock the Platinum Trophy, but it will take a long time. Everything is absolutely beatable.
Multiplayer:
This would point to tart the game also. I have only the normal PS4 with a joypad. However, at any time enter the PS Vita in the game my wife, since the Vita acts as Joypad for the PS4. And it works very well. You can tell there is no delay or whatever. The typical split screen thing of the past has. If both players close enough to each other, then there is only one screen. To remove the players from each other, then the screen is divided dynamically. The whole thing is hard to explain, but I'll try it anyway once xD I run in the top right corner of the screen, the image is divided diagonally. I then heard the upper right triangle of the image, while my wife left lower triangle has as image. Now I move to the left, the image rotates pitch dynamically, so I eventually had the upper half of the picture and should I continue, I have at some point the upper left triangle as an image. This helps quite well the orientation where the other player is. I want the other players, I have to run only in the direction where his shot on the TV's.
From me there full points for the game. Child-friendly, good graphics, great speakers and a lot of gameplay that lasts very long.
Currently there is only one small flaw. I am currently at about 84% in the game when it comes to the solution of all tasks. I have a feeling it's because I have so much unlocked, but every now and then lubricates the game. In the beginning that was never the case. The good thing is, the game saves less permanently, to the game restarts, it is 10 seconds back in the game and lost what one has earned nothing.
