Lego Marvel Super Heroes is the best Lego game I've played. It takes everything that people love about the series (collectables, loads of characters, humor, etc.) and mashes it together with an interesting IP. It seems clear that TT took some ideas from Lego City on Wii U and incorporated them in Marvel such as an "open hub world" which has a lot of things to do. For all the positives, this is a Lego game. There are still legacy issues with this game including the wonky jumping, occasional glitches, and slow pacing that can be irritating. The 6/10 score is based on the fact that not much has changed here, but it still manages to be the best Lego game.
The developer has captured the essence of what makes a great super hero game and found a way to work in every great Marvel hero and villain. I played this after returning home from brain surgery and it filled me with great joy...my son loved it as well...when he could pry the controller out of my hand.
